Question

A dipole with two electric charges of $$2 \, \mu C$$ magnitude each, with separation distance $$0.5 \, \mu m$$, is placed between the plates of a capacitor such that its axis is parallel to an electric field established between the plates when a potential difference of $$5 \, V$$ is applied. Separation between the plates is $$0.5 \, mm$$. If the dipole is rotated by $$30^\circ$$ from the axis, it tends to realign in the direction due to a torque. The value of torque is :
