 P: 1 1. The problem statement, all variables and given/known data Consider an electric dipole located in a region with an electric field of magnitude $$\vec{E}$$ pointing in the positive y direction. The positive and negative ends of the dipole have charges +q and -q, respectively, and the two charges are a distance D apart. The dipole has moment of inertia I about its center of mass. The dipole is released from angle $$\theta$$, and it is allowed to rotate freely. What is $$\omega_{max}$$, the magnitude of the dipole's angular velocity when it is pointing along the y axis? 2. Relevant equations dipole moment p= qd $$\vec{\tau}$$=$$\vec{p}$$X$$\vec{E}$$ U= -$$\vec{p}$$ $$\cdot$$$$\vec{E}$$ 3. The attempt at a solution I attempted to use energy, but I am not sure how to do it correctly - does potential energy equal kinetic? is the potential energy the one described in the above equation?
