Q. No.An electric dipole with dipole moment \(5\times10^{-6}~\text{C-m} \) is aligned with the direction of a uniform electric field of magnitude \(4\times10^{5}~\text{N/C}. \) The dipole is then rotated through an angle of \(60^\circ\) with respect to the electric field. The change in the potential energy of the dipole is:
| 1. | \(1.2~\text{J}\) | 2. | \(1.5~\text{J}\) |
| 3. | \(0.8~\text{J}\) | 4. | \(1.0~\text{J}\) |

A short electric dipole has a dipole moment of \(16 \times 10^{-9} ~\text{C-}\text{m}. \) The electric potential due to the dipole at a point at a distance of \(0.6~\text{m}\) from the centre of the dipole situated on a line making an angle of \(60^{\circ}\) with the dipole axis is:
\(\left( \dfrac{1}{4\pi \varepsilon_0}= 9\times 10^{9}~\text{N-m}^2/\text{C}^2 \right) \)
