A point charge is kept at the centre of a metallic insulated spherical shell. Then

A point charge +q is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.

A point charge +q is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.

A ball with charge -50 e is placed at the centre of a hollow spherical shell has a net charge of -50e . What is the charge on the shell's outer surface ?

A ball with charge -50 e is placed at the centre of a hollow spherical shell has a net charge of -50e . What is the charge on the shell's outer surface ?

A point charge +Q is placed at the centre of an isolated conducting shell of radius R. Find the electrostatic potential energy stored outside the spherical shell if the shell also contains charge +Q distributed uniformly over it.

Shown in the figure a spherical shell with an inner radius 'a' and an outer radius 'b' is made of conducting metarial. A charge +Q is placed at the centre of the spherical shell and a total charge -q s placed on the shell. Charge -q is districuted on the surfaces as :
