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

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.

Both question (33) and (34) refer to the system of charges as shown in the figure. A spherical shell with an inner radius 'a' and an outer radius 'b' is made of conducting material. A point charge +Q is placed at the centre of the spherical shell and a total charge -q is placed on the shell. Assume that the electrostatic potential is zero at an infinite distance from the spherical shell. The electrostatic potential at a distance R(a lt R lt b) from the centre of the shell is

A point charge q'q is placed at distance 'a' from the centre of an uncharged thin spherical conducting shell of radius R=2a. A point 'P' is located at a distance 4a from the centre of the conducting shell as shown. The electric potential due to induced charge on the inner surface of the conducting shell at point 'P' is

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 spherical conducting shell of radius r_(0) carry a charge q_(0) . Then value of electric field inside it is :-
