A short electric dipole has a dipole moment of 16 × 10^-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° with the dipole axis is :

(1/4π∈₀ = 9 x 10⁹Nmπ²/C²)

(1) 200 V

(2) 400 V

(3) zero

(4) 50 V
