A variable capacitor consists of two fixed metal plates located at a distance d from each other, and a movable dielectric plate that can rotate and fit into the gap between the metal plates (figure). All plates have the shape of a semicircle of radius R, and the gaps between the dielectric plate and the capacitor plates are negligible in comparison with d. Neglecting edge effects, find the moment of forces M acting on the dielectric plate,
