spherical shell

I think it is b because at all the points inside the spherical shell eletric field is =0 as there is no charge present inside the shell

is my answer rite?

nthing mentioned

lol

Sorry din saw the options thers no need for conductin, non conductin

(a) is false.. as V can be zero if charge on shell is nonzero and some charge is outside at such a distance and configuration... so that V comes to be negative inside shell

(b) is false as E inside shell is zero.... for any charge configuration...

(c) is also false... because... how will it always be zero at all points in shell..

hence (d)

what about :

yes D.

a)if potential inside it is zero then it necessarily electrically neutral
not necessary.... charges can be distributed in such a way dat pot is zero..

b)electric field in a charged conducting spherical shell can be zero only when the charge is uniformly disturbed
not at all..
if we take a gaussian surface in the inside of the conductor .. we will get E=0 always.

c)electric potential due to induced charges at a point inside it will always be zero
not ncessary... this is opp of point a.

opsie din see only that thread is closed.. likhne me busy the.. [3]
