Statement1: |
The velocity of a body at the bottom of an inclined plane of a given height is more when it slides down the plane compared to when it is rolling down the same plane |
|
Statement2: |
In rolling down, a body acquires both kinetic energy of translation and rotation |
|
a) |
Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1 |
|
b) |
Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1 |
|
c) |
Statement 1 is True, Statement 2 is False |
|
d) |
Statement 1 is False, Statement 2 is True |

(a) In sliding down, the entire, the potential energy is converted into kinetic energy. Which in rolling, the same part of potential energy is converted into KE of rotation, therefore linear velocity acquired is less |
