Question

Two discs A and B are mounted on a vertical axle. Suppose the discs have moment of inertia as I and 2 I respectively about an axis. Disc A is given angular velocity ω, using the potential energy of a spring compressed by x _1.Similarly the potential energy of a spring compressed by x ₂gives an angular velocity of 2ω to Disc B. Considering that both the discs rotate in same direction .Find the ratio x ₁/ x _{2 :}
