Rotational Motion question

2019 · 9 Apr · Shift 1 · Q54

JEE MainPhysicsRotational MotionMCQ+4 / −1
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 centre of mass at the bottom of the incline is same, the ratio of the maximum heights they climb is :
  1. A
    20 : 15 : 14
  2. B
    4 : 3 : 2
  3. C
    2 : 3 : 4
