An electric dipole of mass m , charge q , and length $\displaystyle l$ is placed in a uniform electric field $\displaystyle \overrightarrow{\mathrm{E}}=\mathrm{E}_0 \hat{i}$. When the dipole is rotated slightly from its equilibrium position and released, the time period of its oscillations will be :
