Question

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 ‘$\overrightarrow{E}$; such a way that dipole axis makes a very small angle with the electric field, ‘$\overrightarrow{E}$'. The angular frequency of the oscillations of the dipole when released is given by.

• A. $\sqrt{\frac{4qE}{3ml}}$
• B. $\sqrt{\frac{8qE}{3ml}}$
• C. $\sqrt{\frac{4qE}{ml}}$
• D. $\sqrt{\frac{8qE}{ml}}$
