The electrostatic potential due to an electric dipole at a distance 'r' varies as

If the electric potential on the axis of an electric dipole at a distance 'r' from it is V, then the potential at a point on its equatorial line at the same distance away from it will be

The electric potential due to an electric dipole at an axial point, distant r from the dipole is related to r as
