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