A charge `Q` is placed at the centre of a spherical conducting shell. Choose the correct option.

[" An charge "q_(1)" is placed at the centre of a spherical conducting shell of radius "R" ."],[" Conducting shell has a total charge "q_(2)" .Electrostatic potential energy of the "],[" system is "]

A charge q is placed at a distance of 2R from the centre of a spherical conducting shell of radius R. What is electrical potential, due to charges induced on the shell, at a point which is farthest from the point charge ?

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.

A conducting sphere that carries a total charge of -3q is placed at the centre of a conducting spherical shell that carries a total charged of +5q. The conductors are in electrostatic equilibrium. The charges on the inner and outer surfaces of the shell are respectively.

A point charge q is placed with in the cavity of an electrically neutral conducting shell whose outer surface has spherical shape. Then,

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 :
