Two small rings each of mass m are connected to the block of same mass m through an inextensible massless string of length l Rings are constrained to move over smooth rod AB Initially the system is held at rest as shown in Fig Let u and be the velocities of ring and block respectively when string makes an angle 60 with the vertical m m m B
