The rotating systems shown in the figure are identical. In the left system, identical movable masses are positioned a distance R from the axis of rotation while in the right system, these masses are positioned a distance R/2 from the axis of rotation. You release the identical hanging blocks simultaneously from rest, and call tL the time taken by the block on the left and tR the time taken by the block on the right to reach the bottom, respectively. The bar, pulley, and rope have negligible mass, the rope does not slip, and there is no friction in the axle of the pulley. Under these conditions, what is tR/tL?
