AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A mass \(m\) is in rest on an inclined plane of mass \(M\) which is further resting on a smooth horizontal plane. Now, if the mass \(m\) starts moving under gravity, the position of centre of mass of system will
- A remain unchanged
- B change along the horizontal direction
- C move up in vertical direction
- D move down in the vertical direction and changes along the horizontal
Answer & Solution
Correct Answer
(C) move up in vertical direction
Step-by-step Solution
Detailed explanation
The given situation is shown in the following figure. Clearly when mass \(m\) starts moving under gravity, hence net force on the system in horizontal direction is zero. Therefore, centre of mass of the system will not move in horizontal direction. Now, for vertical direction…
