This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
• Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Your interview went quite well plus aptitude marks = top 10 for you.

Congrats!

- 4 years, 1 month ago

No chance of top 10.I know a guy paean who is scoring as high in 90.and mine is 73.so its quite tough.but I expect a rank of within 100.BTW what's the highest in kvpy from yours state.I don't know sarthaks but his is mostly in 78-80.

- 4 years, 1 month ago

68-70 Nimay Gupta

- 4 years, 1 month ago

Ohk.

- 4 years, 1 month ago

Well according to your interview experience . you will easily get 80+ or even 90.

According to that if you equalise last year your rank will be in the range 25-50 (considering difficulty the same as last year).

I Got about 70 in test and 81 in interview ended with 59 .

My friend got 73 in test and 75 in interview ended with around 50.

- 4 years, 1 month ago

Yeah top 10 is really difficult . one of my friend got 86 in test and 64 in interview lasty year to get air 14

- 4 years, 1 month ago

Any idea about what he told your father?

- 4 years, 1 month ago

No nothing much he asked me where is your father.I just introduced him.And he told something which I didn't hear awe stood a bit away from him...He seemed to be a good person.

- 4 years, 1 month ago

Can you please help me? A particle of mass 'm' moves under a force given by F= -kx^n.Find time period of oscillations if spring constant is k. Here n is any odd integer.

- 4 years, 1 month ago

Ha Ha it reminds me of my friend's interview last year . he was asked the time period for F = -kx^3 . IDK But the professor told him F = -Kx where K = kx^2

Hence time period = 2pi*sqrt(m/kx^2) i know its not logical at all but one of professors of the panel told my friend this :P :P

- 4 years, 1 month ago

Did they tell the actual answer ?

- 4 years, 1 month ago

Ya its of the form 8x(o)^((1-n)/2)/w(n+1)int(sin@^\((2/n+1)d@)).with @ varying from $0-π/2$ and $w^2=2k/m(n+1)$ Here the numbers $2/n+1)$accompanying $sin@$ is the power that sin has been rairaised to.and the no$1-n/2$accompanying the x(o)term is a power .

- 4 years, 1 month ago

Why will it not depend on amplitude?

- 4 years, 1 month ago

Ya it will intact the amplitude is the x(o)term.Hey try putting $.sin@=e^(iy)-e^(-iy)/2i.$Most probably the binomially expanding yieldmsome thing but then that's not in closed form. No don't work it becomes tedious.

- 4 years, 1 month ago

OK so it has a value of (√π)/2T\((n+3)/2(n+1)/$T(n+2)/(n+1)$). T is the gamma function

- 4 years, 1 month ago

How did you do it?I tried doing it with normal integration and things are getting very tedious?

- 4 years, 1 month ago

Ya substituted=x(o)(sin@)^(2/n+1).Although I don't know whether its closed form exists of the integral.But next let me Think

- 4 years, 1 month ago

Well this kind of problem has been asked in jee but was somewhat easier . If i can reckon correctly it had something proportionality constant (alpha)

- 4 years, 1 month ago

Yup the problem mentioned smthing additional like small amplitude,i also remeber.

- 4 years, 1 month ago

Well i did SHM arhive in september 2015 but i marked that question coz i was not able to do that at first shot thats why i remember otherwise there are 100's of problems in archive

- 4 years, 1 month ago

I found this question in some PDF related to SHM.

- 4 years, 1 month ago

How did you solve it?

- 4 years, 1 month ago

Yup closed form does exist use beta function and then gamma function done.

- 4 years, 1 month ago

Well that's not in scope of JEE Atleast although i love gamma and beta functions.

@A E Can you share pdf?

- 4 years, 1 month ago

But many trignometric integrals as well as integrals of the form (x)^a(1-x)^b can be solved under 1 minutes (and it has appeared as a previous jee question where normal method was very long).

Thus it is worth learning even from jee point of view i guess.

- 4 years, 1 month ago

I learnt it coz i loved integrals when it was taught to us! and yeah that helped only in AITS :p

- 4 years, 1 month ago

Did you had any backlogs at the end of class 11?

- 4 years, 1 month ago

Yep many i had . one of my backlog is still there which i haven't overcame FLUID MECHANICS . In chemistry i mostly didn't got Organic of 11th which i improved in 12th . in maths combinatorics troubled me and it still sometimes coz its a kind of topic which you cant master completely .

- 4 years, 1 month ago

I don't have it now,but it was in some PDF related to MIT's open course ware.Try googling it,I suppose its still on their site.

- 4 years, 1 month ago

So what did you get I don't know beta functions much.

r

- 4 years, 1 month ago

I have not solved it till end.You may directly use beta function's defination to evaluate that integral.Just look up on brilliant wikis.

- 4 years, 1 month ago

What's m here?

- 4 years, 1 month ago

Best of luck @Harsh Shrivastava.for your interview tomorrow.do share your experience tomorrow.just stay calm and give your best.you gonna rock it☺☺

- 4 years, 2 months ago

Thnx!

- 4 years, 2 months ago

Wish you all a prosperous holi! :)

- 4 years, 1 month ago

Yup same to you..........

- 4 years, 1 month ago

Same 2 u bro .....

- 4 years, 1 month ago

Happy holi to all 😀

- 4 years, 1 month ago

Be confident , there main target is to check your confidence , they will try to just confuse you in your concepts itself and they will question you continuously , you just need to answer them with full confidence and correctness . And never answer those q which you don't know as wrong answers are not encouraged there and be upto the point , don't add extra waste things to your answer .

- 4 years, 3 months ago

Thanx for your suggestions.will they be asking questions from all the 4 subjects.

- 4 years, 3 months ago

Depends , for me , they ask my favourite subject (Physics ) and then they asked for maths also .

- 4 years, 3 months ago

What was your stage 1 marks?.does it any way matter in stage 2??

- 4 years, 3 months ago

My score was low due to Bio, it was 66.5 , however in second stage they dont ask your scores , they are not interested in that.

- 4 years, 3 months ago

my score in bio is just 11.total 72.75.did you chose any special topic of interest for it??and tell me how did you prepare?we have got mock interviews organised by our school.And they call scientists for that even.so even those who qualify the first stage by a small margin perform well in interview.any way I am also planning to go with phy.

- 4 years, 3 months ago

Your score in 1st stage matters for selection , in second stage its obvious that u will get good score , I didnt do anything special for interview , just searched net for other people experiance.

My score in Bio was just around 6 :P

- 4 years, 3 months ago

11 is big no in bio my score was 0.75😂

- 4 years, 2 months ago

will bio question would be asked to a pcm student

- 4 years, 3 months ago

I can't really gurantee that , but according to me they won't do such things . They understand the problem of students .

- 4 years, 3 months ago

Yup all the best @Harsh Shrivastava

I Will give just one advice. clearly say if you dont know an answer . dont blindly guess . stay calm, cool take your time to think upon the problem. you will rock it

- 4 years, 2 months ago

Thnx!

- 4 years, 2 months ago

in my school only 3 people have been selected 1 sa and 2 in sx

- 4 years, 2 months ago

mine is 14.

- 4 years, 2 months ago

Hey looks like you qualified nsec.from your discussion.this is indeed a grt achievement considering the fact that you are in 11.which state and about your kvpy(when is it)

- 4 years, 2 months ago

Mine is 14/2 =7th rank

- 4 years, 2 months ago

How is class 12th jee preparation is it more difficult than class 11th?

My class 11 is about to end.

- 4 years, 2 months ago

Nothing is difficult in this whole world ... stop thinking about that and let the studies keep going...

- 4 years, 2 months ago

I Would not say difficult (class 12) just its a bit bigger than class 11 in terms of syllabus . but class 12 mostly has 55-60% weightage in JEE So you can understand its importance.

- 4 years, 2 months ago

@Harsh Shrivastava.can you share with me some questions that theyasked you in your interview.

- 4 years, 2 months ago

I was the last one to be interviewed so they asked me easy questions.

First they asked me C1+C2+C3+C4+....Cn prove this in two ways.

Then they asked a multinomial type question .

Then an easy physics question was asked.

Then some easy electrophilic addition question was asked.

That's all.Best of luck!

- 4 years, 2 months ago

How was aiits? @Spandan Senapati @A E @Aniswar S K

I committed so many silly mistakes! :( Dont know when will i stop it :(

Srsly i dont know why i commit so many mistakes :(

My score=20+27+48(cmp)

- 4 years, 1 month ago

We have a screwed up schedule here.I told you.Here they conduct exams from 6-9pm and they don't put the answer keys even.How did you get the answer keys......I will be telling tomorrow.

- 4 years, 1 month ago

6-9 pm!!

Overall howasit?

- 4 years, 1 month ago

Ya it went nice.In Physics I think one and didn't match.That rolling one It must be $(8/35)v/ug$.

- 4 years, 1 month ago

I think answer is matching, coming out to be 3/7 v/ug many of my fnds also got 3.

- 4 years, 1 month ago

Well the friction will change its direction may be I did some calc mistake but its like this initially it acts backward so time taken for w to become zero=(v/2R)*(2/5MR^2)/fR.=v/5ug.and for v to become zero its v/ug.So w becomes zero first then v=4v/5at that instant.Next friction supports rotation and opposes translation so 4v/5-ft/M=5ft/2M(t=8/35)OK then we needed to add with the initial.so that t=3/7..Oh I missed that......Got it thanks.

- 4 years, 1 month ago

Maths was good.Chem seemed easy this time.Let's hope for best.Chill bro.I have exam tomorrow(chem practical)and I have bunked almost class(or absent).So I don't know even how do a simple salt analysis....(☺☺)And although I had done some in preparing for OCSc last yr I don't remember any.......

- 4 years, 1 month ago

Hey spandan, one doubt in the question posted by aniswar , I solved it by iaor method.But then I tried solving by force torque method that is by drawing individual fbds but could not solve it.My doubt is what forces will act on the particle from ground frame?

- 4 years, 1 month ago

Weight of the particle,contact forces by the rim..........But we need to analyse what sorts of acceleration it has.

- 4 years, 1 month ago

I was doing a calc mistake, got my mistake, and yeah result is same in both cases ☺

- 4 years, 1 month ago

Good....Were any answers wrong in phy and maths....Were did you get the keys from

- 4 years, 1 month ago

My center gave us key and some are wrong.I am posting solution to aniswars problem, do verify it.

- 4 years, 1 month ago

Ya.I checked the key it's so incorrect....Maths in a matrix I got-4(Hyperbola)The physics is wrong as well.Esp the first 2 questions.....(Now as per the incorrect key I got (33+25+57).Don't know but in maths the coefficient of(term independent of x is given wrong)...And they also gave that meso compound one wrong.Seriously I hate fiitjee exams for their incorrect answer keys.....

- 4 years, 1 month ago

Yeah m,any are wrong i dont know why but in every exam it occurs :\

- 4 years, 1 month ago

And the SHM was wrong as well energy will change as they stick...And time period and amplitude will change as well.......Careless people.Allen in this regard is grt.I have given n their xms twice and never was there a single wrong and.

- 4 years, 1 month ago

Why shud enrgy change?Also why shud even time period change?

See archive page number-65 jee advanced 2016 multi choice question 1 for a similar question.

- 4 years, 1 month ago

Allen isn't great in this regard :

- 2 years, 9 months ago

Oh yes you are right.I thought the ball was dropped when the other was at mean position.Rather its given that its the extreme........silly me.:)

- 4 years, 1 month ago

Lol many of these kinds of mistakes are committed by me also.We must stop making these mistakes!

- 4 years, 1 month ago

@Spandan Senapati - Yah i got it now. First i considered even atmospheric pressure thats why i got some extra variables. Thanks.

- 4 years, 1 month ago

@Spandan Senapati -- in that 65th question how to relate the rate of increase of temperature and speed of piston?? i tried something like PdV + VdP = nRdT. dV=Adx & dP=kdx/A since P=kx/A. and then divide both sides by dt. but then i am not getting that 3/8 in the answer.

- 4 years, 1 month ago

For 64 make use of the fact that the max theoretical increment in temperature accounts for the increase in internal energy =Increment in potential energy so $nCv(T-To)=Mgh$ and $nRTo=(p+∆p)V$.It's a valid supposition that initially the Tempnof the air inside is $To$

- 4 years, 1 month ago

Hey there is a thing that the piston is nt massless so Weca t equate the forces perhaps.

- 4 years, 1 month ago

@Spandan Senapati, @Harsh Shrivastava, @A E try this https://brilliant.org/problems/down-she-goes/

- 4 years, 1 month ago

I am getting a non integral answer, I used energy conservation and the fact that since string is inextensible,velocity along them would reduce to zero though I may be wrong.

- 4 years, 1 month ago

I haven't tried it but is the bead fixed.Or the situation is just like a catenary.(chain hanging between 2 walls)

- 4 years, 1 month ago

And I guess we are gonna receive the Kvpy results soon.Let's hope for the best.Lastyr it was declared on 22nd.March

- 4 years, 1 month ago

Why are you worrying? You will get through easily ☺

I am doubtful about mine.

- 4 years, 1 month ago

Arey don't worry .You will get through as well...You qualified NTSE stage 2 as well I guess

- 4 years, 1 month ago

I also wrote momentum impulse equations.

- 4 years, 1 month ago

bhai ye dekh

ghanta mushkil tha :P agar 5-6 number grace de di to mere to 100 paar jayenge number :P balki set-3 tha sabse mushkil maine saare set dekhe the haina bhai ? tere kitne aajenge btade bhai plz ?

- 4 years, 1 month ago

now i'm feeling bad about bragging too much without even knowing my real marks , just hope i get what i want btw math mein fatti padi hai bhai help @Prakhar Bindal

- 4 years, 1 month ago

@Spandan Senapati @Harsh Shrivastava @A E Sorry to Disturb

For us Differential Calculus got over.

Have you got any source for challenging problems??

I searched brilliant and mostly found integration problems!

- 3 years, 11 months ago

For us definite integration is over.So I solve integration ones from Ronak aggarwals feed.Differential calculus I too want some good source.I think harsh can help us better.some questions from ronaks feed are quite tough.do try them.

- 3 years, 11 months ago

Sure. Lets see what harsh has got to say!

- 3 years, 11 months ago

For us even function is not over!!!!

BTW I guess there is an acute shortage of diferrential calculus problems !

- 3 years, 11 months ago

@Spandan Senapati @Harsh Shrivastava A question!

A parallel plate capacitor is completely filled with a dielectric sheet of thickness d and relative permittivity k is placed on a horizontal tabletop. The lower plate is glued with the tabletop and the dielectric slab is glued with the lower plate. The plates are square of edge length l and mass of the upper plate is m. The plates are given a charge +q and -q, then the upper plate is shifted horizontally by a small distance x along one of its edges and set free. Find the period of oscillation of this plate. Thickness d of the dielectric is much smaller than the edge length l.

- 3 years, 10 months ago

Thanks let me try.

- 3 years, 10 months ago

Us the answer.$.T=2\pi L/Q(2m\epsilon kd) ^(0.5)$.I solved using energy conservation as there would be fringing fields here and directly calculation of the force may be difficult....

- 3 years, 10 months ago

In the answer there is a factor of 8. I don't know how they got it. T=(8l/q)(e0kmlx/d)0.5 and pi is not there!!

- 3 years, 10 months ago

Yes I know it's not gonna be a shy. It's gonna be a periodic motion with probably constant acceleration(I think) I will retry it.i didn't notice that the width of the dielectric is quite less. That's the error.

- 3 years, 10 months ago

Try this way let an external agent displace the upper plate by a distance X then $W(agent) +W(capacitor) =0$ .Since for an isolated system in the absence of dissipation forces the energy remains conserved. Now since electric force is conservative $W(capacitor) =-dU$ Where the second term represents the change in potential energy. Since no external potential is applied$U=Q^2/2C$.Now when we displace the plates by $x$ say then $U=L^2\epsilon /\sqrt d^2+x^2$.Now put that in the equation $F=dU/dx$. and terms of the order $x^2$ can be neglected. This gives $F=\psi x$. But we don't have any agent performing so the force applied by other charges on this is $f=-F$. So the plate exhibits SHM.Find $T=2\pi /\omega$

- 3 years, 10 months ago

I am sorry. It's incorrect. Didn't notice that the dielectric has thickness much smaller than the edge length....

- 3 years, 10 months ago

It would be better with a diagram. But I don't see what thickness means here. Anyways we begin by noticing that when the plates of a capacitor are displaced then the capacitance of the system is given by $A\epsilon/d.$where $A$ is the projected common area.So Here $A=L(L-x)$ . Now $C=kL(L-x) /d$. Force by the other charges on this plate is $F=-dU/dx$. $U=Q^2/2C$.Note that the charge remains the same but $\sigma$ changes..Using this you get $ma=-kQ^2d/2m\epsilon L^3.$ Now that we have acceleration as negative means it's gonna come back to its natural position, overshoot and head to an amplitude, return back. So $t=4\sqrt (2x/a)$ The constant $4$ for in one complete cycle it covers$4x$ distance.So this yields$t=8L/Q\sqrt (mk\epsilon Lx/d)$ .I used d as the distance between the plates. God knows how it's the thickness. Lol. Got It? And the thing wrong in the previous solution was the expression for capacitance...

- 3 years, 10 months ago

Nice one!!

This means we must not expect everything to be shm!!

- 3 years, 10 months ago

And to the other question(on pressure) that you had posted I got $V^2=\alpha b/(k^2-1)$.If the dielectric slab completely fills the space then studying the distribution of charges the net field at position ofa face of e dielectric is $\sigma /2\epsilon (1+1/k)$.The charge on the face is $\sigma (1-1/k)$(on!y magnitude).Thus thethe pressure is $b=\sigma^2 /2\epsilon (1-1/k^2)$(for the limiting case).Again $\sigma =CV/A=k\epsilon V/d$.Plugging in the prev exp gives $b=V^2\epsilon /2d(k^2-1)$Thus $V^2=\alpha b/(k^2-1)$.....Although I think if not completely filled then the dependence will be on C specifically(and thus $t,k$

- 3 years, 10 months ago

I took the field to be sigma/k. But we must consider the field due to other charges excluding the charge layer itself

- 3 years, 10 months ago

Yes...I hope you got it

- 3 years, 10 months ago

I have a nice question in physics. Will post it soon.Do try.

- 3 years, 10 months ago

All the past qualifiers/having experience of interview are requested to comment on this forum.@Prakhar Bindal,@Aniket Sanghi and all.

- 4 years, 3 months ago

Which topic will you chose in physics?

I guess I would chose maths and sub topic integration.

- 4 years, 3 months ago

I will most probably go with black holes or relativity.I need to discuss with my teacher.

- 4 years, 3 months ago

Will they ask from our favorite topic?

- 4 years, 3 months ago

Ya they mainly polarise on your fav topic.but there are even chances that they will ask from all the sub.like for a pcm student they can ask bio even but of a low level.

- 4 years, 3 months ago

I am not doing any special preparation for it.

Just revising definitions.

Wbu?

- 4 years, 2 months ago

Oh my school is providing us excellent facilities like interactive sessions,interview by professors,school teachers etc.those are very helpful.the interview official by iisc have started from today.is nt resonance organising interview sessions in your state??

- 4 years, 2 months ago

No.Best of luck for interview!

BTW do you know abt a full open test of Fiitjee scheduled at 12th Feb.Its like AITS.

- 4 years, 2 months ago

Its peanuts in front of AITS. The paper is Hell simple!. Last year the top scorer got more than 95% in mains .

The advanced paper is also just too simple.

- 4 years, 2 months ago

Is that guy kushagra juneja???

- 4 years, 2 months ago

Nope . he doesn't give much fiitjee tests as my friend tells me who studies at fiitjee punjabi bagh .

I Got AIR 2 In AITS Open test advanced with a score of 411/504 missing the 1st rank by 1 mark (topper scored 412) :P . sorry if i have boasted myself :P

- 4 years, 2 months ago

Only few get to the level so high so that they can boast :)

- 4 years, 2 months ago

Grt!!!performance..I don't call this as boasting.you just said your rank.

- 4 years, 2 months ago

how is paper ,very tough?

- 4 years, 2 months ago

The paper is very easy . Mathematics was just too simple . On checking last year's paper i found that i score 76/80 in math paper 2 and 81/88 in paper 1 .

Chem was as usual bad in paper 1 involving some pretty bad inorganic chemistry . as a result i got 62 in paper 1 .

Physics was quite easy . the reason for my not so good in physics (66 in paper 2 and 68 in paper 1 ) was that i hadn't done fluids at that point coz i missed classes of surface tension. so i left 2 problems in paper 2 and one in paper 1 of it .

- 4 years, 2 months ago

Thanks,and AIR 2 is just awesome,you are truly an inspiration.

- 4 years, 2 months ago

Ya I have heard abt it.and fiitjee also has iit genius exam on 5th Feb.that looks good.I think I will appear.wbu??

- 4 years, 2 months ago

From my school only I have been selected so nothing special is done :(

- 4 years, 2 months ago

Congrats bro!!for kvpy.you also like basketball??can you do those dunks??

- 4 years, 3 months ago

Well I can touch the rim and yeah, in some street courts ,I can dunk where rim is low, also my school ring is very low so I can easily dunk there.

BTW u follow NBA?'coz this season there are some hell weird transactions.

- 4 years, 3 months ago

Not near but I perform those lay up shots,free throws well.anything inside the d and its in the basket if in my hand.but our rings are quite high.so I can't dunk.even the best players of our team can't.

- 4 years, 3 months ago

Ya I love NBA.but I can play only in school.we have a screwed up time table in fiitjee(5 days)+school.so its becoming tough for me to go up with the game.

- 4 years, 3 months ago

And those fake shots??you know some??

- 4 years, 3 months ago

Well I have played state level basketball so yeah,I am familiar and well practiced with those fakes,crossovers,layups with added spices and 360° shot.

Mine favourite team is GSW,yours?

Also you play at which position?I am 5'10'' and rigid so I play usually center+shooting guard.

- 4 years, 3 months ago

Congrats to u too.Nsep+kvpy is awesome!!

What abt rmo?

- 4 years, 3 months ago

Ya I did rmo this year as well.will have a hard time preparing for inao,inmo,inpho.

- 4 years, 3 months ago

Woah god!!!

Rmo+nsep+kvpy+nsea is hell awesome.

I can't clear nsep and nsea.

Preparing for inmo from where?

Geometry always kills me.

- 4 years, 3 months ago

I am not one who is comfortable with maths all times.last year I also qualified for inmo and next was 31.!!although my rmo score this year was high(83) compared to the cutoff but inmo needs a craze for maths which I think I don't have.I am solving prev q papers and our inmo camp will start from 2 jan

NISER,Bhubaneswar.yours????

- 4 years, 3 months ago

Some institue in Kolkata.

- 4 years, 3 months ago

So it would be a grt experience for you to go to Kolkata and appear for the interview.I guess it would be IISER.BTW what's going on in fiijee??

- 4 years, 3 months ago

Our starting in fiitjee was slow so we are bit behind.

Maths=Bionomial theorem

Phy = SHM

Chem =Isomerism.

- 4 years, 3 months ago

In our batch phys thermodynamics,maths-triangles,chem-goc over but next topic has not been started yet.merry Christmas bro!!!

- 4 years, 3 months ago

Merry chrstmas to you too bro!

How was your aiits 3?you gave it??

- 4 years, 3 months ago

Sorry to interupt but last year's AIITS 3 (class 11th one) Was horrible for us atleast. with a pretty bad pattern (10 Multi correct 10 integer) and -2 marking made it hell. for a top 50 rank only a score of 105 was needed of 210!

- 4 years, 3 months ago

Ya this year was exactly the same.I am scoring 151 as per the answer key.fiitjee sometimes surprises students with such pattern.I had last encountered such in class 9 aiits-3.and I had just screwed up the paper.and no sorry this is an open forum and you can post freely anytime.

- 4 years, 3 months ago

Can you tell what's the general scenario of students as they move from 11-12.as in our centre I used to see that a guy used to top I all exams.but in class 12 that guys best rank is 65(most probably).I can't just account for this.Is it that students do better in 12??

- 4 years, 3 months ago

My Rank almost remained constant in class 11 as well as 12 . My average rank in class 11 was about 15-20 and in 12th it is about 20-25 . but yeah sometimes it happens . my one friend used to get top 10 ranks in aiits in class 11 but he is getting 300-400 rank dont know why although he is too good at PCM.

One of my other friend was getting 300 rank class 11 but now he is consistently getting in top 50 .

So it depends on you!

- 4 years, 3 months ago

Pattern was same for us but paper was easy but then also I made manyy silly mistakes.

- 4 years, 3 months ago

Gave it but really really sucked it.Made many unworthy mistakes :(

How was yours ?

- 4 years, 3 months ago

Went well.I didn't do many mistakes as I attempted anly those I knew.but I think mi could have done better in chem if I had studied b-c family.

- 4 years, 3 months ago

Giving ftre?

- 4 years, 3 months ago

Nope!!I will study for monthly test.dont you have it on Monday??its for the cm batch.

- 4 years, 3 months ago

And fiitjee bbsr is making the q this time on an all India basis.

- 4 years, 3 months ago

Cm batch is not in our center.But we do have monthly tests.

https://brilliant.org/problems/a-problem-of-my-book-5/?ref_id=1296492

In this problem ain't answer coming out to be 4.75 something?

Exact answer : $\sqrt{\frac{7(\pi (\pi + 2))}{5}}$ ??

If not,can you please post the solution bro? thanks!

- 4 years, 3 months ago

I am not getting the problem.can you tell how can I go to this question.

- 4 years, 3 months ago

- 4 years, 3 months ago

OK as much as I recall I had got the and as 4.01.o I entered it as 4.

- 4 years, 3 months ago

Hmm

Basically what i did was to use the fact that normal reaction is providing restoring torque here.

Am a right?

- 4 years, 3 months ago

Its the weight that will provide+there can be friction as well.as its not slipping.so what I did was wrote the energy and since friction is static I differentiated it.something that we do in Lagrangian mechanics.this is irrelevant here.but you can try out this approach.static friction ensures that energy is conserved

- 4 years, 3 months ago

Oh yes!Energy conservation is useful here.I forgot the torque due to friction.

What resources do you use in physics,also how can i improve in physics?

- 4 years, 3 months ago

I am passionate about the sub.currently I am working out a guide to physics problems part-1(springer) for inpho.is is a collection of problems from the PhD exams of MIT,Moscow tech etc.also I follow Arthur beiser(seriously try this if you wanna feel the essence of modern phy)and David morin.a simple advise I can give is love the subject ike you do basketball.then everything becomes interesting

- 4 years, 3 months ago

You know what i love physics and maths.

Being not good in physics can't steal my love for it.I enjoy every moment i spend on thinking hard on a tough physics problem and get the best feeling when i can sometimes crack them.

- 4 years, 3 months ago

Yeah!that's the spirit. don't worry dude you.eep working and you will surely succeed.and I think there is nt any notion like Mr x is not good is not good in this subject??BTW what are you doing for inmo??

- 4 years, 3 months ago

I am reading about inversions in geometry coz they seem to be pretty good for solving problems involving a circle and some points.But i did not studied for inmo in the last week bcoz of some backlogs in jee-maths and physics and chem..

- 4 years, 3 months ago

And chem?? 😀😀

- 4 years, 3 months ago

Organic chemistry seems to be good.

But hate inorganic from bottom of my heart and i am okay with physical.

wbu?

- 4 years, 3 months ago

I like chem.but don't pay enough time to it.so I secure a bit less.

- 4 years, 3 months ago

And what do you use for maths.....BTW I too love physics and maths a lot!!!!

- 4 years, 3 months ago

Grt!!for maths I don't do anything special.I was more focused on olympid maths in class 10 but now jee math is good.so I mainly do q from packages,some Olympiad problems related to jee.and class notes.

- 4 years, 3 months ago

Grt....and all the best for your interview

- 4 years, 3 months ago

Thanks a lot.

- 4 years, 3 months ago

And my and was 2π√(π-2)(R/g)

Here is my experience

My score in aptitude test wasn't that good (about 71) due to my poor performance in biology (6 or 7).

But my interview went quite good (i was give 81/100 in interview).

i could not figure out and i told him that . he said no problem and then i was directed to biology mam.she asked me to sit down and take some juice and be relaxed . after 1 minute she asked me what have i studied in biology . i readily said cell theory as that was the only topic i studied for interview. she asked me some basic questions what is a cell , tissue , organalle's , name some organalle's and there functions. in explaining all these i said the word disease . she turned the topic to disease and asked me what is a disease name any three viral , bacterial disease . in the last i told here cholera (bacterial disease) then she asked me which bacterium causes cholera . i couldn't recall and i told her . my interview was over and they asked me whether i will go for iit or not i told not yet decided :P

i was happy but not very satisfied came out my dad told me that my interview lasted exactly 18 minutes .

i had snacks at the iit canteen (burger , pizza) etc and came back home .

just remain confident dont give wrong answers thats it

all the best

- 4 years, 3 months ago

I must really appreciate your method of presentation.thank you!!!

- 4 years, 3 months ago

So even you filled maths as your favorite subject,you were asked easy questions on it.

- 4 years, 3 months ago

yup i was asked tough questions of chemistry :P

- 4 years, 3 months ago

brilliant experience . !! . ☺

- 4 years, 3 months ago

Ohh i dont remember as such :P :P . i am lazy to check it up again!

- 4 years, 3 months ago

hehe!!

- 4 years, 3 months ago

Wishing you all a happy and prosperous new year 2017.cheers!!!!

- 4 years, 3 months ago

to you to still 1 hour to go

- 4 years, 3 months ago

Same to you!

- 4 years, 3 months ago

How was inmo?

I don't know why the hell the coordinator changed timings here and it was from 12 to 4 here :(

And I could not know about this change thus lost 1 hour :'(

Did 1 complete ,2 almost complete and 75% of one.Could have done better if time was there :(

- 4 years, 3 months ago

Never mind.you put your best efforts and that's what matters.mine was fine.I was not prepared but somehow managed to solve 5,6,1,4,3.(the last I am not sure)but I think I could have solved all 6 if I had prepared right from the start.let's wait for results.BTW the timing for us was also 12-4.just chill now.

- 4 years, 3 months ago

So how will you manage with IMO and IPHO?

Congrats for your selection in INMO!

So is IIT your aim?

You can post images easily by using this trick.I assume you know how to post pictures in questions , so just go and post any image you want to post in post a problem section and then copy the link thatll come and paste it to comments.

- 4 years, 3 months ago

No inmo is quite tough.cutoffs will be high and they don't give much partials.let's hope for best.I am not so serious abt it.ya I am targeting ipho.quite early to say as I am exploring different fields.but I want to do research in the field of physics.as for jee I don't mainly polarise my attention to that.

- 4 years, 3 months ago

I will try then.I haven't posted any q since long time.I will do it soon.when is your interview?ours is on 17-19 Feb?quite late.

- 4 years, 3 months ago

Mine is on 24th Jan.

- 4 years, 3 months ago

May I know how you are preparing??just wanted to know.

- 4 years, 2 months ago

Hey can you help me.how do you post the pictures of wedges,etc.I wanna post a q but I can't upload it.can you help??

- 4 years, 3 months ago

@Harsh Shrivastava.how was your interview???

- 4 years, 2 months ago

Well I think my interview went well but don't know what will happen.

I was last one to be interviewed in my center.

- 4 years, 2 months ago

@Prakhar Bindal.how are your preparing for INO.I wanted to know abt astronomy.I had given INAO in class 10.but that was like the worst exam.for me.can you advise some thing.thanx.

- 4 years, 2 months ago

Actually i am not preparing for INAO And might not give it too . It has indeed clashed with my board practicals which cant be neglected and postponed. I Might give INCHO+I feel its high time for me just work on my weak topics for JEE coz this time only 6 days are there between board exam end and JEE Mains .

- 4 years, 2 months ago

Guyz @Prakhar Bindal @Spandan Senapati can you please suggest me how not to make silly mistakes in the exam and how to keep calm temperament during tests? Thanks!

- 4 years, 2 months ago

I won't be the perfect one to advise.but in exams I don't become so happy even if I solve e toughest problem.I just move in with the hope of completing the entire paper(if not at least trying it full)and for avoiding silly mistakes you need to be very careful right from filling the omr to completing the exam.just after you solve a q read the opt. carefully and then only mark.1-2 silly mistakes will ocurr even with toppers but notmaking many distinguishes them.also it would be beneficial if you solve subjective q as then you can reach the final Sol.

- 4 years, 2 months ago

I Am trying to work on them . might be increasing concentration will help

- 4 years, 2 months ago

Best of luck @Prakhar Bindal,@aniket sanghi and all for INAO,INCHO tomorrow.

- 4 years, 2 months ago

yup and same to you!!

- 4 years, 2 months ago

My god! which school is that?

- 4 years, 2 months ago

You don't know its DAV chandrasekharpur....Not to boast of but my school has got a splendid history and has nurture d some great prodigies.......

- 4 years, 1 month ago

whereas it boasts of fiitjee integrated

- 4 years, 2 months ago

@Prakhar Bindal how was INCHO

- 4 years, 2 months ago

mine was Average. Organic was doable but That coordination compounds question and last deuterium one sucked .

And yeah i felt paper was lengthy for 3 hours .

I Had a bad time struggling with calculator . they gave pretty bad values in physical and i am not good at using a calculator

- 4 years, 2 months ago

same was the case with me too many people told they did organic and left the rest!

- 4 years, 2 months ago

@Spandan Senapati Did u write FTRE??

- 4 years, 2 months ago

No I didnt

- 4 years, 2 months ago

How was INPHO

- 4 years, 2 months ago

Fine.I was able to solve most except part(2 bits) of the last q and q5.due to less time.it was quite a lengthy paper

- 4 years, 2 months ago

How many mechanics questions were there?

Can you post the paper?

- 4 years, 2 months ago

No I can't.it was a qpaper cum and sheet.1 !each q and the other 1 relayed to mech and em

- 4 years, 2 months ago

Wow each question had mech that's awesome BTW expecting selection?

- 4 years, 2 months ago

No I didn't mean that only 1 was a perfect mech q.and another party mech+electromagnetic induction.ya I hope so that I get selected.if not I have got a chance next year.BTW I am enjoying my Olympiad journey.

- 4 years, 2 months ago

Hey are aiits 3 results out.I will have to focus on jee till feb28 (day of results).our administration is quite lazy

- 4 years, 2 months ago

Hey @Spandan Senapati inmo scorecards are out.

I got 51 😭 time issue really affected me 😭

How much u got?Also plz tell abt scores from your region.

- 4 years, 2 months ago

Grt score.how many had you solved.I can jut guess y marks.I haven't got yet.that's quite a good score I must say ad you HD some 3 hrs only to solve the paper. Tell some more marks from your region.

- 4 years, 2 months ago

3-4.

Rest of the scores from my region are below 40 I guess highest after me being 38 probably.

BTW tell me yr score after you get them.

- 4 years, 2 months ago

We have got marks 69, 53,52,51,48,40,40,36.

- 4 years, 2 months ago

Bro rank in aiits? Top 5?

Mine is very poor 167 :(

- 4 years, 2 months ago

Now let's see if you can tell it.you will I know.that's easy.my rank=(no of distinct letters in your name).

- 4 years, 2 months ago

Awesome !

- 4 years, 2 months ago

Where did you see the result?

- 4 years, 2 months ago
