A dipole comprises of two charged particles of identical magnitude \( q \) and opposite in nature. The mass \( 'm '\) of the positive charged particle is half of the mass of the negative charged particle. The two charges are separated by a distance \( 'l' \). If the dipole is placed in a uniform electric field, \('\bar E '\), in such a way that dipole axis makes a very small angle with the electric field, \('\bar E' \). The angular frequency of the oscillations of the dipole when released is given by:
