Charge in a shell!
Electricity and Magnetism
Level
3
A charge of + 2 μC is situated off-centre of a hollow spherical metallic shell. Then,
no charge appears on the outer surface of the shell
– 2μC charge gets non-uniformly distributed on the inner surface of the shell
– 2μC charge gets uniformly distributed on the inner surface of the shell.
- 2μC charge gets non-uniformly distributed on the outer surface of the shell

Electric field inside a hollow spherical shell is always zero.
Here the shell has a charge inside placed asymmetrically inside the shell. For electric field to be zero, an equal and opposite charge must be induced non uniformly inside the shell to cancel out the electric field due to the placed charge.
Do note that if charge was placed at the center (symmetrically), the induced charge would be equal, opposite and uniformly distributed.
