A short electric dipole has a dipole moment of $16\times10^{-9}\ C\,m$. The electric potential due to the dipole at a point at a distance of 0.6 m from the centre of the dipole, situated on a line making an angle of $60^\circ$ with the dipole axis is: ($\frac{1}{4\pi\epsilon_0}=9\times10^9\ N\,m^2/C^2$)
