Dipole in Non Uniform Electric Field

An electric dipole of moment vec(P) is placed in a uniform electric field vec(E) such that vec(P) points along vec(E) . If the dipole is slightly rotated about an axis perpendicular to the plane containing vec(E) and vec(P) and passing through the centre of the dipole, the dipole executes simple harmonic motion. Consider I to be the moment of inertia of the dipole about the axis of rotation. What is the time period of such oscillation ?
