A dipole with two electric charges of 2µC magnitude each, with separation distance 0.5µm, 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∘ from the axis, it tends to realign in the direction due to a torque. The value of torque is :
