An electric dipole is situated in an electric field of uniform intensity E whose dipole moment is p and moment of inertia is I. If the dipole is displaced slightly from the equilibrium position, then the angular frequency of its oscillations is [MP PET 2003]

\[{{\left( \frac{pE}{I} \right)}^{3/2}}\]

\[{{\left( \frac{pE}{I} \right)}^{1/2}}\]

\[{{\left( \frac{I}{pE} \right)}^{1/2}}\]

\[{{\left( \frac{p}{IE} \right)}^{1/2}}\]
