A circular ring having mass M 4 m and radius R is attached to a small smooth ring of mass m kept at point A The ring is threaded onto a horizontal fixed frictionless wire B A Initially the bigger ring is held horizontally alongside the wire in such a manner that initially the planes of both the rings are at 90 to each other and the planes of smaller and bigger rings are perpendicular to the plane of the paper x y plane Now the bigger ring is released from rest After release the planes of smaller and bigger ranges remain perpendicular to the plane of paper x y plane 100 the angular speed of bigger ring at the instant it is vertical is g B 23R 5 g 6 V3R y C 10 g 85R X D g 3R
