A rigid horizontal smooth rod AB of mass 0.75 kg and length 40 cm can rotate freely abput a fixed vertical vertical axis through the midpoint O. Two strings each of mass 1 kg initially at rest are placed at a distance of 10 cm from O on either side of the rod. The rod is set in rotation with an angular velocity of 30 radian per sec and when the rings reach the ends of the rod, the angular velocity in rad/sec is?
