Electric Charges and Fields · Electric dipole

A rigid dipole undergoes a simple harmonic motion about its centre in the presence of an electric field E⃗1=E0x^\vec E_1 = E_0\hat x. If another electric field E⃗2=2E0(y^+z^)\vec E_2 = 2E_0(\hat y + \hat z) is introduced to the system, what will be the percentage change in the frequency of the oscillation (approximate)?
