MHT CET · Physics · Motion In Two Dimensions
A particle moves along a circular path with decreasing speed. Hence
- A its resultant acceleration is towards the centre.
- B it moves in a spiral path with decreasing radius.
- C the direction of angular momentum remains constant.
- D its angular momentum remains constant
Answer & Solution
Correct Answer
(C) the direction of angular momentum remains constant.
Step-by-step Solution
Detailed explanation
The direction of angular moment remains constant as the angular momentum is a vector quantity, and its direction is perpendicular to the plane of motion. As the speed decreases, the linear momentum decreases, but the angular momentum remains constant due to the conservation of angular momentum.
