this is a jee question does anyone has any idea how this works?

Hey guys which test series will you join apart from fiitjee?

i am preferring allen over resonance what do your guys think?

- 9 months, 1 week ago

If online tests are okay for you, then: assuming you are in FIITJEE, you must be having access to myPAT - did you try them? Besides there is AIiTS, if you want to give tests comparable to JEE Advanced (unlike AITS!).

Besides, there's Embibe. [A note for Embibe: recently, they have started charging Embiums (virtual currency on Embibe that you can either purchase by real-world cash or earn by solving questions on Embibe) for various services on the site.]

I Dont have plans as such now .why do you need other test series?

Hey Guys i have got a problem . In my CPP This problem doesnt have answer . can you guys solve and tell me the answer i am getting w = 2

A Particle is at the lowest point of a smooth wire frame in the shape of parabola lying in the vertical x-y plane having equation x^2 =5y (x,y are in meter) . after slight displacement particle is set free. find angular frequency of oscillation

take g = 10

Bro! Do you have some good questions which are more easily solved by Energy method than Force method ?

I u have , then share some bro!

And I have got one good q , you may like to solve

- 9 months, 4 weeks ago

By Energy Method , Answer is coming 2 .

Let me also try by Force Method .

- 9 months, 4 weeks ago

By Force method also , answer is coming 2.

But by Torque method , I dont think the answer will come easily!!!

- 9 months, 4 weeks ago

I am also getting 2...same approach

- 9 months, 4 weeks ago

I am also getting w as 2.

I used the approximation that for small displacement, tanz=b/a=a/5 where b and a are position coordinates of the particle at some instant and also that for small z,tanz is almost equal to z.

- 9 months, 4 weeks ago

even i used the same approach

- 9 months, 4 weeks ago

Will solve it and tell

- 9 months, 4 weeks ago

Hey guys how much did you got in AITS Part test 3 advanced?

today i attempted the paper at home at JEE Timings . i got 205/360 in it . what about you?

- 10 months ago

Can non 12th graders get these papers?

- 9 months, 4 weeks ago

Yet to attempt bro

- 9 months, 4 weeks ago

227

- 9 months, 4 weeks ago

Cool so 227 was your score in AIITS?

How Much you got in AIITS Held on monday?

- 9 months, 4 weeks ago

I was also shaken Bro by hearing 227 in AIITS - 6 !!!!!!

Now , it's okay 227 in AITS is okay!

- 9 months, 4 weeks ago

same here how much did you socred in AITS 3?

- 9 months, 4 weeks ago

Bro ! Your score in AIITS 6 ?

- 9 months, 4 weeks ago

I didn't gave it.

- 9 months, 4 weeks ago

Oh ! Okay! Never Mind ! ☺

Any Special Reason?

- 9 months, 4 weeks ago

Have anyone downloaded the Full test 1 and 2 papers from net on 20th December . I forgot that time and now I am not getting that URL opened .

Help me Guys

- 10 months ago

http://aiits.fiitjee.com

Check out this link for the papers

- 10 months ago

Thanks a lot bro for the links i needed them desperately! :)

- 10 months ago

which full tests?

- 10 months ago

Full test 1 and 2 that are to be downloaded from net .

- 10 months ago

oohhh..

- 10 months ago

- 10 months ago

Damn ..i also forgot

- 10 months ago

Has the results for NSEP, NSEC, NSEA declared? -@Prakhar Bindal

- 10 months ago

nope who told you? it will be out in first week of jan

- 10 months ago

See inside question booklet- Its written list of students above having score above MAS will be displayed on 22 dec

- 10 months ago

I Know that but scoring above MAS Does not imply you qualify for INO's

- 10 months ago

But that information is sufficient bro at least to me as here scores are also displayed and practically 5 students used to get selected from here per exam !!

A uniform rod of mass m and length l is hinged about a point and is initially horizontal.Now the rod is released and it can rotate freely about an horizontal axis passing through A.

Find the tension in the midpoint of the rod when it becomes vertical.

My answer is not matching , I am getting 17/8 (mg) .I used integration.

Thanks.

- 10 months ago

Thus tension at topmost point,the point just below the hinge, comes out to be 3mg/2, but it not physically realisable,what say?

- 10 months ago

those who are getting 17mg/8 would have ignored the weight of half rod while writing equilibrium equations

- 10 months ago

Edit:

I made a mistake, now I am getting 9mg/8 ,it seems to be correct since it is given in the option while rest of the answers, 13mg/8 and 17mg/8 are not in option.

- 10 months ago

$$\dfrac{9mg}{8}$$ is the value excluding the weight of the half rod

- 10 months ago

What is the meaning of "excluding the wt if half rod"?

- 10 months ago

Tension in midpoint of rod = weight of the one half + centripetal force.

centripetal force comes out to be 9mg/8

- 10 months ago

Centripetal force 9mg/8?? havent you taken into account the hinge reaction?

- 10 months ago

hinge reaction!?

- 10 months ago

Yup there will be some hinge reaction too from the hinge on the rod

- 10 months ago

but what it has to do with tension in mid point ?

- 10 months ago

seems like we have solved the problem using different approaches

- 10 months ago

can you share yours?

- 10 months ago

Actually i have to leave now

- 10 months ago

In writing equilibrium equation along the rod for the rod have you taken into account the weight of half rod??

- 10 months ago

Yup indeed!

- 10 months ago

i am getting 13mg/8

- 10 months ago

I am also getting 17mg/8.

- 10 months ago

@Archit Agrawal how much are you getting in AIITS?

- 10 months ago

N u?

- 10 months ago

227

- 10 months ago

i am getting $$\dfrac{13mg}{8}$$.

Used integration.

- 10 months ago

Yes, it is 13mg/8.

- 10 months ago

- 10 months ago

and do you feel some answers wrong?

- 10 months ago

I do

- 10 months ago

What did you did for that q whose answer is not given in phy?

- 10 months ago

7 BC Int 4 - 5

- 10 months ago

I agree with you

- 10 months ago

i got 1 to integer 4 and 7 i agree BC

In Math matrix 4 last 2 parts seem to be wrong

In chem many seem to be wrong

- 10 months ago

I agree i chem as well

- 10 months ago

How much score u all are getting in aits??

- 10 months, 1 week ago

i did not gave this AITS Due to KVPY Camp at IISER Kolkata

what was your score in AITS-1 Or the recent AIITS-5?

- 10 months, 1 week ago

Hii guys I am from fiitjee lko

- 10 months, 1 week ago

Hi Iko?

- 10 months, 1 week ago

Hello!.

- 10 months, 1 week ago

How to improve chemistry??

I really suck at it and it always pulls my rank down a lot.

We have just started organic chemistry.

- 10 months, 1 week ago

and if you keep away FIITJEE AITS Organic chemistry is the most scoring part of chemistry along with inorganic.

- 10 months, 1 week ago

Organic chemistry takes a lot of time and patience to master.

In beginning i also faced this problem but fortunately we were given sufficient time to revise it again and again. in beginning you will forget reagents named reactions will remind you of biology.

Just one advice do GOC Properly . It is the KEY For ORGANIC.

I Had to do it again in march this year coz i didn't studied it properly in 11th .

- 10 months, 1 week ago

- 10 months, 1 week ago

Inorganic i cant say. i am myself learning it.

For physical i dont feel there is much problem.

Physical is just like know some formulae and concept and apply them to problems thats all!.

which part of physical are you facing problem?

- 10 months, 1 week ago

Gaseous state .

- 10 months, 1 week ago

Gaseous state? . that seems odd.

Real gases (theoretical part) is a bit tough to understand. rest its a simple formula application chapter

- 10 months, 1 week ago

How was AITS? @Aniket Sanghi @Archit Agrawal

- 10 months, 2 weeks ago

I got value of w as $\sqrt{\dfrac{20\sqrt{3}}{4-\sqrt{3}}}$

Is this exact value correct?

- 10 months, 2 weeks ago

Check out my set all problems posted by me

- 10 months, 3 weeks ago

Guys scores in today's Aiits?

- 10 months, 3 weeks ago

My score 175 with this answer key

Answer keys I feel are wrong - [ My SET A]

1. Chem that graph one (ABCD) (+3)
2. That SCl2 (OCH3)2 one (ABC) (+3)
3. That density one density is not acceptable (bonus +3)
4. That electfonegativity one (ABC) (+3)

Maths

1. Maths that cos[pi/x]cos () one 1 (ABC)(as x tends to zero the cos tends to 0 (second cos) ) (+3)
2. Match f (x) = that sin [] that long one . I got discontinuous at 5 points . (+2)
3. Int 1.that f(x) = X sin (quadratic ) one . I got at 5 points (as it was cont. At -1,0,1,2. (+6)
4. Int 8(that f (x) = xln^2x one. Ans 1 (+6)

Physics

1. That mgcotx and mgtanx one (+3)
2. That ring one (BC) (+3)
3. That particle velocity and acc (Only A) (+3)
4. That int of pulleys ans 16 (bonus +4)
5. Ans omega finding one answer 20. (Bonus +4) .

If I consider these all then my score (at max) can be 221.

Your arguments ? Where am I wrong?

- 10 months, 3 weeks ago

And bro math integer 1 function is discontinuous at x = 1 check again!

- 10 months, 3 weeks ago

Agreed . Did a mistake took that outer x as [x] .Finally cold and cough showed it's effect.

- 10 months, 3 weeks ago

Bro my cold and cough is also continued. PPM Level in delhi still above the danger mark

- 10 months, 3 weeks ago

Oh! Sad ! Future of world getting smoggy!

- 10 months, 3 weeks ago

I Agree with all of your chemistry problems i got exactly the same answers as you got Hifi!!!

Math 1st one yeah i too got ABC

Q2 Dont know

Q3 No i think its correct. i got 6 in the exam

Q4 I Too got 1

Physics

I Agree with first 4

But in last i think omega is correct

- 10 months, 3 weeks ago

My 183 from this key n I think some ans are wrong. N share your scores

- 10 months, 3 weeks ago

If all these keys are corrected then your score @Archit Agrawal?

- 10 months, 3 weeks ago

201

- 10 months, 3 weeks ago

Answers which i feel are wrong are

Chemistry (graph ones ) should be ABCD

H2O2 One should be bonus density cant be 26.5

OCH3 One about incorrect statements i got ABC To that

Physics

Wedge one where mgcotx is given but mg/tanx is not

integer physics one in which velocity was asked it was turning out to be 16 but i ticked 4

- 10 months, 3 weeks ago

Yep that density one also , I felt that error!!

- 10 months, 3 weeks ago

Phy multiple choice Q6 ans must be only A Maths int Q4 it must be 1

- 10 months, 3 weeks ago

Yeah what's yr score in olympiad ( nsep , nsec, nsea )

- 10 months, 3 weeks ago

Yup A Only i didn't do Q4 Of math

- 10 months, 3 weeks ago

N @Archit Agrawal How much r u getting in olympiads?

- 10 months, 3 weeks ago

My 174 from this key

- 10 months, 3 weeks ago

Why do we not talk on slack now?
