A short electric dipole has a dipole moment of  $32\times {10}^{-9} \mathrm{Cm}$. The electric potential due to the dipole at a point at a distance of 0.18 m from the centre of the dipole, situated on a line making an angle of ${60}^o$ with the dipole axis is : $\left(\frac{1}{4{\mathrm{\pi \epsilon }}_0}=9\times {10}^9\mathrm{N}{\mathrm{m}}^2/{\mathrm{C}}^2\right)$
