A point charge Q 1 C is fixed at the centre of an insulated disc of mass 1 kg The disc is resting on a rough horizontal surface Another charge Q 1 uC is fixed vertically above the centre of disc at a heighth 1m The disc is displaced slightly in horizontal direction by a small displacement x Friction is sufficient to prevent slipping Let radius of disc be R and the corresponding angular displacement of disc is 0 X If angular acceleration is a y x 10 0 rad sec then find y z R h 1m DE sufficiently rough
