A bob of mass m carrying a positive charge q is suspended from a light insulating string of length l inside a parallel plate capacitor with its plates making an angle `beta` with the horizontal as shown in figure. The plates of the capacitor are connected with a battery to establish an electric field E between the plates with its upper plate negatively charged. Find the period of small oscillations of the pendulum and the angle between the thread and vertical in equilibrium position of the bob
