The electric potential on the axis of an electric dipole at a distance r from its centre is V. Then the potential at a point at the same distance on itsequatorial line will be
The electric potential due to a dipole at a point on its axial line at a distance r from its center is given by: V = 1/4πϵ0 p/r²
where p is the dipole moment. On the equatorial line of a dipole, the potential at any point is always zero because the contributions from the positive and negative charges cancel out.

(d) Zero. The electric potential due to a dipole at any point on its equatorial line is always zero. This is because the contributions from the positive and negative charges cancel each other out, as they are equidistant from the point and their potentials have equal magnitudes but opposite signs, resulting in a net potential of zero.
