An electric dipole is placed at an angle of $\displaystyle 30^{\circ}$ with an electric field of intensity $\displaystyle 2 \times 10^5 \mathrm{~N} \mathrm{C}^{-1}$. It experiences a torque equal to $\displaystyle 4$ N m. Calculate the magnitude of charge on the dipole, if the dipole length is $\displaystyle 2$ cm.
