Two discs A and B are mounted co-axially on a vertical axie. The discs have moments of inertia I and 2I , respectively, about the common axis. Disc A is imparted an initial angular velocity 2 omega using the entire potential energy of a spring compressed by a distance x_(1). Disc B is imparted an angular velocity omega by a spring having the same spring constant and compressed by a distance x_(2). Both the discs rotate in the clockwise direction. The ratio (x_(1))/(x_(2)) is |
