    The frequency of oscillation of an electric dipole moment having dipole moment p and rotational inertia\[I,\] oscillating in a uniform electric field E is given by

    A)  \[(1/2\pi )\sqrt{I/PE}\]

    B)  \[(1/2\pi )\sqrt{{{P}^{E}}/I}\]

    C)  \[(2\pi )\sqrt{{{P}^{E}}/I}\]

    D)  \[(2\pi )\sqrt{/I{{P}^{E}}}\]

    Correct Answer: B

    Solution :

    We know, \[n=\frac{1}{T}\] and \[T=2\pi \sqrt{\frac{{{I}_{S}}}{{{M}_{S}}{{B}_{H}}}}\] Hence according to condition \[n=\frac{1}{2\pi }\sqrt{\frac{pE}{I}}\]
