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