Question

Two charges each of magnitude $0.01 ~\mathrm{C}$ and separated by a distance of $0.4 \mathrm{~mm}$ constitute an electric dipole. If the dipole is placed in an uniform electric field '$\vec{E}$' of 10 dyne/C making $30^{\circ}$ angle with $\vec{E}$, the magnitude of torque acting on dipole is:

$4 \cdot 0 \times 10^{-10} ~\mathrm{Nm}$

$1.5 \times 10^{-9} ~\mathrm{Nm}$

$1.0 \times 10^{-8} ~\mathrm{Nm}$

$2.0 \times 10^{-10} ~\mathrm{Nm}$
