Question

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

Select the correct option:

$4.0 \times 10^{-10} \mathrm{Nm}$

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

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

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