Two equal charges q of opposite sign separated by a distance 2a constitute an electric dipole of dipole moment p. If P is a point at a distance r from the centre of the dipole and the line joining the centre of the dipole to this point makes an angle theta with the axis of the dipole, then then potential at P is given by (f gt gt 2a) where (p = 2 qa) |
