A spherical conducting shell of inner radius r and outer radius r2 has a charge Q a If a charge q is placed at the centre of the shell then surfacecharge density on the inner and outer surfaces of the shell are Q q q 4 r and 2 b If a charge q is placed at the centre of the shell then surface charge density on the inner and outer surfaces of the shell are 9 and 2 9 2 4 r 2 4 r 9 4 r 2 4 r c If a charge q is placed at the centre of the shell then surface charge density on the inner and outer surfaces of the shell are Q q and 2 2 4 r d The electric field inside a cavity with no charge is zero if the shell is spherical and non zero if the shell has any irregular shape
