An electric dipole consists of two particles each of mass 1 kg separated by 1 m carrying charges 1 μC and –1 μC respectively. It is equilibrium in a uniform electric field of 2 \times10^4\Vm^{−1} . If it is deflected by a small angle 2°, minimum time taken by it to come back again to the mean position is ( in seconds )
