A large horizontal uniform disc can rotate freely about a rigid vertical axis passing through its centre O . A man stands at rest at the edge of the disc at a point A . The mass of the disc is 22 times the mass of the man. The man starts moving along the edge of the disc. When he reaches A , after completing one rotation relative to the disc, the disc has turned through
