So the kvpy interview is over.I am gonna share my experience.For me it was scheduled to be held at 9:00 am in NISER,Bhubaneswar. I reached there by 8:15.quite a far place.abt 22km from Bhubaneswar.It was adjacent to IIT,Bbsr.My interview started at 9:45 am after the completion of 2 students.The first one is a friend of mine(I don't know him much) who said after his that the interview board is quite friendly.that seemed a good gesture.So when I entered I just introduced my self,what I liked to do.etc.They asked what I had for breakfast and it was maggi for me.so they readily asked(chem) what chemical led to the controversy in maggi case.I didn't know.but anyways the person had himself told that this is not related to interview.so now of started.my topic was wave-particle duality,photoelectric effect and modern phy....somi was asked to explain photoelectric effect.on board which I did.then the physics prof asked me to split the work function into constituents.I did that it was binding energy+energy to remove that from the influence of all other interacting forces.then the mam asked on wave prop.then maths.I knew him as he is the director of institute of maths(where I had attended inmotcs in class 10,11)even he had felicitated me this yr for being 3rd in state in rmo.so he asked to prove that sum(j^99)j=1,2,3,4,5.was divisible by 5.I did that quite easily and could even generalise the case although it wasn't asked.the interview board seemed quite happy.I proceeded to factorise and proof the generalisation. And he didn't allow me to complete as he saw the first few steps and said "oh come on you can do after this quite easy" then something on relations.which I replied that I have not studied.and he said that it wasn't a big thing.I could do it anytime.then I was asked some conversions in organic although I didn't know them he didn't tell much and asked what I will do in future I said that I will do research (in mathematical aspect of physics) and they seemed quite impressed.and the next was a staple q(do you really want to join jee or do research)I genuinely replied research(as that's what I really wanna do).it came to an end and theybjust asked if I wanted anything to get clarified. I just asked what I can do to promote my interest as a student.The chem one replied that I was doing really well and I will do so.that made me feel quite ecstatic.and that was the end.later the director of niser(perhaps)wanted to meet my father.as he seemed to be quite happy with my perforomance.Later I went to canteen(some drinks)and returned.Believe me it was very big and great campus.and on way I even went to IIT bbsr.it is still under construction.nothing much but the field there is quite big.and it will look beautiful after some years.

@Spandan Senapati 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. A E · 3 weeks, 2 days ago

@A E 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 .

@Prakhar Bindal 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).

@A E 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 Prakhar Bindal · 3 weeks, 2 days ago

@Spandan Senapati 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).

@Harsh Shrivastava 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.

@Aniswar S K 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 \(To\) Spandan Senapati · 2 weeks, 1 day ago

@Aniswar S K Ya I s just saw and solved q 65.That's quite easy.Use conservation of energy for the entire system.We can find out the height h(but that would involve solving some hell weird exp) So they indirectly gave that h.And the other thing is simple the exp of the gas is adiabatic.Most of the qseem to be from energy conservation Spandan Senapati · 2 weeks, 1 day ago

@Spandan Senapati It seem all of us are quite habitual to this habit of silly errors. i too lost many points in AITS Open test due to my negligence and of course my laziness. What happened was i did physics pretty good which i attempt first (score 48/62) then got into chem . clean bowled didn't knew many Multi corrects . due to this made a bubbling error (4 marks puff!) . Then switched to maths again did well (43/62) . then came to chem at last . i could have scored easily upto 32/62 but got only 15 due to my silly errors and my laziness (i didn't got a nice sleep last night and hence slept from 12 pm to 12:30 pm in paper 1) :P (paper was from 9:30 to 12:30) . but somehow i came over this sleepiness and managed to remain awake whole paper 2 :P Prakhar Bindal · 3 weeks, 2 days ago

Log in to reply

@Shubham Dhull Another thing that I must add is when you are calculating the interaction energy between the sphere and the point charge you place the image charge and calculate their interaction energy with the point charge right.But now this must be divided by 2.Because of space symmetry(I don't know the general proof although I had once verified that the statement is true).........I hope you got the mistakes in your solution...

Log in to reply

@Shubham Dhull No you need to place 2 image charges.Because the first charge as you did is correct \(-qr/d\) at a distance\(R^2/d\)from the centre but now we need to do 2 things 1)Maintain the electrical neutrality of he sphere and2)Make the spherical surface an equipotential so This could be done by placing another image charge \(qr/d\) at the centre.And another thing that is wrong is the interaction energy between the sphere and the point charge is what you have calculated perhaps.The question asks for mutual interaction energy between charges induced..And there is a mistake in calculation of the interaction energy between the sphere and point charge.....

@Aniket Sanghi A no of methods can be used perhaps.I know 2-3.One involves integration,another simply placing the image charges and calculating their interaction energy(divide by 2 because of space symmetry).

As far as subjects are concerned they asked pretty simple questions like equation of a straight line and the one perpendicular to it. And Bernoulli's theorem and its applications. Hydrogen bonding. And some graphs from kinematics. Finally they asked what do you want to do in your future. I told that I haven't decided. And they told that it was an honest answer. And thats it!!

@Aniswar S K I was in a hurry when I solved the q.So let me try again..Use energy conservation for the entire system.Change in potential energy=-negative of the change in the internal energy.And that for an adiabatic process \(∆U=∆(PV)/(y-1)\).So this will yield \(h=25/2=12.5cm\).And hydrogen has \(Cv=(5/2)R\) Spandan Senapati · 3 weeks, 2 days ago
