A mass m is at rest on an inclined plane...

A mass `m` is at rest on an inclined plane of mass `M` which is further resting on a smooth horizontal plane. Now if the mass starts moving, the position of centre of mass of the system will :
.

A

remain unchanged

B

change along the horizontal

C

move up in the vertical direction

D

change along the vertical while remains same along the horizontal

Text Solution

Verified by Experts

The correct Answer is:
D
( c) The mass move under the influence of gravitational pull which acts along the vertical. Thus `CM` changes along vertical while it remains unchanged in the horizontal direction.
