The magnitude of torque acting on an electric dipole when placed at right angles to a uniform electric field is $2 \sqrt{2} \times 10^{-2}$ Nm. Magnitude of the torque acting on the dipole when dipole moment makes 45° with electric field will be:

$\sqrt{2} \times 10^{-2}$ Nm $2 \times 10^{-2}$ Nm $\sqrt{2} \times 10^{-1}$ Nm $4 \times 10^{-2}$ Nm

$2 \times 10^{-2}$ Nm

The correct answer is Option (2) → $2 \times 10^{-2}$ Nm
