A rod OA of mass m and length L hinged at end O can rotate smoothly in vertical plane about horizontal axis passing through O It is released from a horizontal position as shown in the figure and strikes a block of mass M kept vertically below O at distance L on a smooth horizontal surface The block after collision moves on the smooth vertical circular B track of diameter L such that the force exerted by the circular track on the block at third of its weight If the rod after collision rotates through an angle 30 from the he ratio of masses M m A 30 M
