Two discs A and B are mounted coaxially on a vertical axle. The discs have moments of inertia / and 27 respectively about the common axis. Disc A is imparted an initial angular velocity 200 using the entire potential energy of a spring compressed by a distance x,. Disc B is imparted an angular velocity by a spring having the same spring constant and compressed by a distance x. Both the discs rotate in the clockwise direction. The ratio of x/x, is (A) 2 (C) 2 -IN- Two discs A and B are mounted coaxially on a vertical axle. The discs have moments of inertia / and 27 respectively about the common axis.
