A uniform thin rod AB kept in horizontal plane of length L and mass m is undergoing fixed axis rotation about an axis passing through end A and perpendicular to the horizontal plane as shown The kinetic energy of section AP of rod is equal to kinetic energy of section BP of rod at any instant Then the ratio of length AP and length AB that is AP is equal to AB O 72 A P m L O 21 3 B
