46 A capacitor consists of two stationary plates shaped as a semi circle of radius R and a movable plate made of dielectric with permittivity and capable of rotating about an axis O between the stationary plates Fig 3 34 The thickness of the movable plate is equal to d which is practically the separation between the stationary plates A potential difference V is applied to the capacitor Find the magnitude of the moment of forces relative to the axis O acting on the movable plate in the position shown in the figure O O R Fig 3 34
