A thin ring, a disk and an annular cylinder, of same mass M , are released from a point 3.6 m from the ground up an inclined plane of 30^ inclination. The ring and the disk have the same radius R . For the annular cylinder, the outer radius is R and the inner radius is R / 2 . Times taken by the ring, disk and annular cylinder, respectively, to reach the ground are in the ratio,
