1. The problem statement, all variables and given/known data Electric dipole makes small angle with uniform electric field. Find the frequency of the oscillation using dipole moment p, moment of inertia I, and field magnitude E. 2. Relevant equations Torque=I*(angular acceleration)=I*(theta)'' Torque=p*E*sin(theta) 3. The attempt at a solution What I did was set PE*sin(theta)=I*(theta)'' But then I need to solve a differential equation which is absolutley not supposed to be required for this class. Is there a way to find this frequency without solving a differential equation?
