1I 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
f
f
for a spherical shell
a)if potential inside it is zero then it necessarily electrically neutral
b)electric field in a charged conducting spherical shell can be zero only when the charge is uniformly disturbed
c)electric potential due to induced charges at a point inside it will always be zero
d)none of these
ans d

33Sorry 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 :

1yes 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.
