Find the frequency of oscillation of an electric dipole, of dipole moment p and rotational inertia I, for small amplitudes of oscillation about its equilibrium position in a uniform electric field of magnitude E.
I think that the relevant equations are τ = I α , τ = pEsinθ , and α is the second derivative of θ
The Attempt at a Solution
τ = I α
pEsinθ = I d2θ/dt2
Then I don't know where to go on from there. Am I even on the right track? Help?
