Electrostatic Potential and Capacitance

A short electric dipole has a dipole moment of 16×10−916 \times 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∘60^\circ with the dipole axis, is: (14πε0=9×109 N m2/C2\dfrac{1}{4\pi\varepsilon_0} = 9 \times 10^9\ \mathrm{N\,m^2/C^2})

  1. A.50 V
  2. B.200 V✓
  3. C.400 V
  4. D.Zero

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
