Question

Derive the expression for electric field on axial line of an electric dipole.​

Answer 1

Explanation:

Electric field at a point on the axis of a dipole :

(2) We shall calculate electric field E at point P on the axial line of dipole, and at a distance OP = r. (3) Let E1 and E2 be the intensities of electric field at P due to charges +q and –q respectively
