None like him. I don't like praising him but he got AIR-1 in KVPY in 11th. He has won Gold medal for India in Astronomy Olympiad held in Lithuania last year. He also bronze medal in IJSO held in Iran in class 10th.

- 3 years ago

Log in to reply

He seems to be on the right track for AIR 1. but you have to keep in mind that Chitraang Murdia did not have any medals in any olympiads before appearing for JEE but still got AIR 1 by a huge margin .After all everyone starts the Exam from 0 marks no matter how many certificates or medals he may have.

- 2 years ago

Log in to reply

The resistances found in the graphing part are not the actual Rab,Rbc,Rca. For example from the graph we got 5.66 which is not rca but rca-effective which is formed by ab,bc in series which are in turn parallel with ca.

@ALL- it would be of great help if any one could findout a few marks from Andhra pradesh students and report, because they performed exceptionally well in NSEP and knowing their inpho marks will undoubtably reveal significant data,

Also some of you are from Mumbai, so i suppose you can find out your friends marks as well as mumbai has serious talent,

Lastly i would also request those from Kota which is the hub of IIT JEE prep ,@Pranjal Jain to kindly tell any marks (good ones espectially) they know of their friends,

That would be great help :)

@Mvs Saketh how to find field due to induced charges in electrostatics? asked in inpho to calculate force between a metallic sphere and a point charge

- 3 years ago

Log in to reply

Yeah use image theory, we can treat this situation as equivalent to a charge at centre with magnitude q+qR/D and another image charge in the usual position (at LD=R^2 point) (or inverse point of charge (external)) , with magnitude -qR/D and now calculate force using coulumbs law,

This question requires a much deeper understanding of image theory which i fortunately had due to solving many problems regarding it already from online websites,, i believe those who do not know image theory or only know the basics of it will take too long to figure this one out and hence might leave it,, i hope that helps me :P

@Pranjal Jain what do you think would be the expected cutoff for INPHO, this year, i know u didnt give but u might have heard something or so, i got 68 in inpho, , but yes definitely cutoff will be above 50 or 60, or god forbid 70, in which case i am done, but its not predictable,

but ur thoughts?

- 3 years ago

Log in to reply

68, you got it quite nice marks( monster marks), I am here just regretting over myself.

- 3 years ago

Log in to reply

actually bro i commited silly mistakes, i mean i am also tired of telling this repeatedly, but you wont believe that like a stupid idiot, i plotted even graph incorrectly, and almost questions answer part i got wrong values , even though i had a calculator, (because i did not properly plot graphs) i really thank the checker for step marking because if it was objective paper, i would have got 45 or so,

and well, trust me you would have found the paper pretty easy :) (except maybe the last question because it was not mentioned, assume Bohr quantisation, )

- 3 years ago

Log in to reply

this year's paper was difficult that last years' paper

- 3 years ago

Log in to reply

well bro both this year and last year paper was easy, except the black hole problem this year which i think is against the spirit of IPHO that sufficient information must be provided for questions out of syllabus,, and it is wrong to not mention that assume bohr quantisation in the question , because how can one know that a black hole proton atom behaves the same way as a hydrogen atom, also there were too many graphs this year, so indeed cutoff should be a bit lower,

but one thing is sure, it is not really so much paper dependent but more student dependent, if less people perform well, than low cutoff and so on, so no one can really predict, so just relax and wait till march 16

- 3 years ago

Log in to reply

i too had to leave that black hole problem for the very same reason.i thought this years inpho was a bit too mathematical(the 1st question itself) and calculative(the electrostatics question to find potential,thermodynamics question) which is against my liking. I knew almost no theory behind any of the graph questions but managed to get them right by pure mathematics(give any moron a bunch of values and he can plot the graph).According to me ,the best question(to check physics understanding) was the one in which they asked what would happen if angle of incidence=0(that glass slab question).and the hbcse guys answered that very elegantly too.Mathematics must only be used as a language to convey great ideas of Physics.The above question is the one in which one actually understands the meaning of limits(that we can answer for i=0+d and i=0-d (d is very small)but there is no such thing as i=0 exactly).

- 3 years ago

Log in to reply

Well , i agree with the black hole part and also that graph questions were stupid except for the inference from the graph, that was beautiful, like boiling point and latent heat, and yes give any moron values and he/she can plot a graph, that is very true.

But i rather think it was too experimental, and graphing doesnt check any ones innovation, rather electrostats problem was the most beautiful problem i think, but yes i agree one thing surely, that the values they gave sucked, i mean the numbers must be such that they cancel out and give a nice clean value so we know we are right and we can recheck, but the expressions in the electrostatic problems were very long and unfriendly,

i dont know bro, dont raise my hopes too much :P

because this year paper was bit easy , except for the black hole problem but i ended up doin too many stupid mistakes like forgetting to write a 2 in the denominator, plotting T vs t inplace of dT/dt vs t , and all, cost me much,

thanks to step marking though , well yes i can understand that ur statement is based on past year results like 60 percent cutoff in 2014 , and 50 percent was in 2013, but then it was 75 in 2012,,

i guess it all depends on my relative performance now, i hope others too have done silly mistakes like me :P
