Electrostatics

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:
