First of all congrats to all those who have been selected for the interview.Its indeed a great achievement as lot many appear in this prestigious exam .So we have abt 1-2 months left for the interview.So you guys can give suggestions on the interview like which subject to choose,questions related to that etc.I welcome suggestions from you all.From my school we have got 46 selections in which 32 are from SA and rest from sx.

TopNewestSo 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 · 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.Log in to reply

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 .Log in to reply

Why will it not depend on amplitude?Log in to reply

OK so it has a value of \((√π)/2T\((n+3)/2(n+1)\)/\(T(n+2)/(n+1)\)). T is the gamma functionLog in to reply

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.Log in to reply

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

– Harsh Shrivastava · 2 weeks, 6 days ago

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

– Spandan Senapati · 2 weeks, 6 days 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.Log in to reply

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 \(To\)Log in to reply

Ya sometimes they don't.I remember in aiits-2 on checking physics my marks were (-13/67.Yes minus thirteen)☺☺.After the results were out my marks were(62/67).So they do change in case there is a major fault or technical one.But in normal cases they dont careLog in to reply

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 :PLog in to reply

– Spandan Senapati · 3 weeks, 2 days ago

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 · 3 weeks, 2 days ago

ofcourse i get it .Log in to reply

– Spandan Senapati · 3 weeks, 2 days ago

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.....Log in to reply

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.

Although bit seemed somewhere misleading.If the expansions are adiabatic we must have\( PV^y \).And eventually if motion ceases we have pressure of gas=\(P(o)+mg/A\).then volume can't be same........And its a light piston or does have some mass.......Log in to reply

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 \(Cv=(5/2)R\)Log in to reply
