The Self Potential Energy of Continuous Charge Distributions

A ring of rad...

Question

A ring of radius r is kept vertical and a dipole[of charges q and distance l] is kept at the centre of the ring and perpendicular to the diameter of the ring. The ring is positively charged uniformly. Find the potential of the dipole at a distance X from the centre of the ring and along the axial line of the dipole.
