wow! pink!
:P

well bhaiya... delete that pink in vapour pressure question...
woh wrong tha...
gagar answered it ...
Suppose that there are 3 concentric metallic shells placed inside each other.. (radius r, 2r, 4r respectively)
the outermost is given a charge Q
The middle shelll has q charge
What is the charge that flows if The outermost shell is connected to the innnermost shell..
also tell the direction.
see i am sleeping.. sorry for confusing u all.. it wont be 3q :)
But it wont contain Q either... (sorry subash i will check it :)

but u have given that there is a charge x that flows from the outer shell to the inner shell and u didnt mentioned that x charge is induced
no in the inner surface of the innermost shell, there is no induced charge..
pot at outermost shell = (Q+q+q')/4r
pot at innermost = (4q'+2q+Q)/4r
wen we join these two..
both pot will be same.
so, q'= - q/3
so charge on innersphere= -q/3.
chare on outer = Q+2q/3.
hence charge transfered : q/3.
from outer sphere to inner sphere.
lets first see the charge distributions
innermost: 0, x (x flows from outermost to innnermost)
Middle: -x, q+x
Outermost: -q-x, Q+q+x (edited)
This will be the charge distribution...
Can u see this and then try to find the value of x?
Of course intelligent minds think similar :P :D
dont blame me of plagiarism
m gettin it as Q
n ya solly pura q ni padha tha bhayah ...........hcv q is diffrnt there d middle one is earthed n u just gt to find d charge distribution
taking the charge on outer to be Q-q2
and innermost to be q2
and then equating the potentials on the surface of innermost and outermost shells because they are connected
This hint is simple sankara..
1) You have to use gauss' law in the metallic part of the shells
2) Potential fo the outer shell is equated to that of the innermost shell...
i can say that about many of the question of the days.. ;)
if they are at some other place.. dont blame me for that :P
and yeah dont blame me of self praise either :D ;)
I know that i do that a lot.. but then dont blame me for it ;)
