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 center of the dipole and the line joining the center of the dipole to this point makes an angle θ with the axis of the dipole, then the potential at P is given by ( 
) (where, 
).
