A thin, rigid insulated rod of mass m and length l carrying a charge Q uniformly distributed along its length is smoothly pivoted at P. It is placed in between the charged large conducting plates. Disregard gravity. (a) Find the initial acceleration of the rod. (b) Find the angular speed of the rod as the function of angle theta of rotation omega = f(theta), if the rod is allowed to rotate freely.
