358160 An electric dipole is formed by two particles fixed at the ends of a light rigid rod of length \(l\). The mass of each particle is \(m\) and charges are \( - q\,{\rm{and}}\, + q\). The system is suspended by a torsionless thread in an electric field of intensity \(E\) such that the dipole axis is parallel to the field. If it is slightly displaced, the period of angular motion is
