Question

Mention two differences between potential due to a point
charge and potential due to an electric dipole. Also derive an
expression for the electric potential at a point on the extended
axis of an electric dipole.​

Answer 1

Answer:

The electric potential tells you how much potential energy a single point charge at a given location will have. The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle

Derive an expression for electric potential at any point due to an electric dipole. Potential at point P due to the dipole along the equatorial line will be zero as P is equidistant from the two charges
