A space is divided by the line AD into two regions. Region I is field free and the region II has a uniform magnetic field B directed into the paper. ACD is a semicircular conducting loop of radius r with centre at O, the plane of the loop being in the plane of the paper. The loop is now made to rotate with a constant angular velocity  about an axis passing through O, and perpendicular to the plane of the paper in the clockwise direction. The effective resistance of the loop is R. Plot a graph between the induced emf and the time of rotation for two periods of rotation.
