An electric dipole of mass m, charge q, and length $$l$$ is placed in a uniform electric field $$\overrightarrow{E} = E_{\circ}\hat{i}$$. When the dipole is rotated slightly from its equilibrium position and released, the time period of its oscillations will be:

A

$$\frac{1}{2\pi}\sqrt{\frac{ml}{2qE_{\circ}}}$$

B

$$2\pi \sqrt{\frac{ml}{qE_{\circ}}}$$

C

$$\frac{1}{2\pi}\sqrt{\frac{2ml}{qE_{\circ}}}$$

D

$$2\pi \sqrt{\frac{ml}{2qE_{\circ}}}$$
