87. Eq. 22-35 τθ =− pE sin b g captures the sense as well as the magnitude of the effect. That is, this is a restoring torque, trying to bring the tilted dipole back to its aligned equilibrium position. If the amplitude of the motion is small, we may replace sin θ with in radians. Thus, τ ≈− pE . Since this exhibits a simple negative proportionality to the
