A dipole with two electric charges of \(2\mu \mathrm{C}\) magnitude each, with separation distance \(0.5\mu \mathrm{m}\)…

A dipole with two electric charges of \(2\mu \mathrm{C}\) magnitude each, with separation distance \(0.5\mu \mathrm{m}\), 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 :
