A) \[3{{R}_{0}}/2\]
B) \[3{{R}_{0}}/4\]
C) \[9{{R}_{0}}/16\]
D) \[3{{R}_{0}}\]
Correct Answer: B
Solution :
[b] When body rolls dawn on inclined plane with velocity  at bottom then body has both rotational and translational kinetic energy |
| Therefore, by law of conservation of energy, |
 |
 |
(i) |
 |
| When body is sliding down then body has only translatory motion. |
  |
(ii) |
| Dividing (i) by (ii) we get |
