An electric dipole is placed at the centre of a hollow conducting sphere. Which of the following is correct ?

Options

A. the flux of the electric field through the sphere is zero
B. the electric field is zero at every point of the sphere
C. the electric potential is zero everywhere on the sphere
D. the electric potential is zero on a circle on the surface

Answer

A, D

Explanation

An electric dipole is placed at centre of sphere `implies` Net charge enclosed in the sphere is zero Flux is zero. Electric potential is zero on circle which is in the plane i.e. perpendicular to the line joining two charges of dipole.
