Question

A mass m is 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 C.M. of mass of system will: (A) remain unchanged (B) change along the horizontal (C) move up in the vertical direction (D) move down in the vertical direction the vertical along the horizontal

Tardigrade Admin · Accepted Answer

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

Q. A mass m is 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 C.M. of mass of system will:

remain unchanged

change along the horizontal

move up in the vertical direction

move down in the vertical direction the vertical along the horizontal

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
