Question

An electric dipole is placed at the center of a sphere. Mark the correct answer 

(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 1

Correct option (A, D)

Explanation: 

Electric field due to dipole exists inside sphere only a circle on the sphere has zero potential which is equidistant from poles of dipole
