For a spherical shell
If potential inside it is zero then it necessarily electrically neutral
electric field in a charged conducting spherical shell can be zero only when the charge is uniformly distributed.
electric potential due to induced charges at a point inside it will always be zero
none of these
Figure shows three concentric metallic spherical shells. The outermost shell has charge $q_2$, the inner most shell has charge $q_1$, and the middle shell is uncharged. The charge appearing on the inner surface of outermost shell is
A non uniformly shaped conductor is charged then at it's sharpest point
If electric potential of the inner sphere is $10\, volt$ and that of the outer shell is $50\, volt$ then potential at common centre is :-......$V$
A metallic spherical shell has an inner radius ${{\rm{R}}_1}$ and outer radius ${{\rm{R}}_2}$. A charge $\mathrm{Q}$ is placed at the centre of the spherical cavity. What will be surface charge density on $(i)$ the inner surface, and $(ii)$ the outer surface ?
A conducting sphere of radius $r$ has a charge. Then
