1integration ,, i have already posted the answer
The conducting, concentric , hollow spheres A and B have radii a and b
respectively, with A inside B. Their common potential is V. A is now given some charge such that its potential becomes zero. The potential of B now will be ????????????

62dude.. i could not figure the exact set up of this question..
could u explain it again?
1i have posted complete question. its from d.c pandey.
no other information is given in question
62EDITED TO CORRECT MY MISTAKE
wanst that unclear.. sorry dude.. just was not in my mind :)
let charges be q on inner and r on outer shell
kq/b+kr/b=kq/a +kr/b = V
=>q=0!
so kr/b=V
if we earth it or make potential at "a" zero, then let q1 flow to it..
potential at a will be kq1/a+kr/b = 0
q1=-r.a/b
so potential at b will be
kq1/b + kr/b =
-kra/b2+kr/b
kr/b{-a/b+1}
V(1-a/b)
=V(b-a)/b
62sorry dude u are right.. i made a stupid damn mistake last nite.. i think i needed more sleep [1]
Now i hope this is correct .. just check it...
