The following bodies are made to roll up (without slipping) the same inclined plane from a horizontal plane :
(i) a ring of radius R,
(ii) a solid cylinder of radius R/2 and
(iii) a solid sphere of radius R/4. If, in each case, the speed of the center of mass at the bottom of the incline is same, the ratio of the maximum heights they climb is -
(1) 20 : 15 : 14 (2) 10 : 15 : 7 (3) 2 : 3 : 4 (4) 4 : 3 : 2
