O B 6 A light ring of radius r wearing two identical beads A and B each of mass m is hinged at its top point O in such a way that it can rotate freely in its plane about a horizontal axis through the hinge O The bead A is affixed on the ring and the bead B is held so that they occupy positions of the ends of the horizontal diameter of the ring and the system stays motionless The ring is well lubricated so that the bead B can slide with negligible friction on the ring Determine acceleration of the beads immediately after the bead B is released and final angle of rotation of the ring when all motion ceases after a long time due to the little viscous friction between the bead B and the ring Acceleration due to gravity is g
