A particle moving in a circular path with decreasing speed. Which of the following is correct?

A

It will move in a spiral and finally reach the centre

B

Acceleration `veca` is towards the centre

C

Only direction of `vecL` is constant

D

`vecL` constant

Text Solution

Verified by Experts

The correct Answer is:
C
If a particle moves in a circular path with decreasing speed, then only the direction of rotation remains unchanged, so the direction of its angular momentum (L) will remain constant.
