A particle moves in a circular path with decreasing speed . Choose the correct statement.

A

Angular momentum remians constant.

B

Acceleration `(vec a)` is towards the centre.

C

Particle moves in a spiral path with decreasing radius.

D

The directon of angular momentum remains constant.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Angular momentum is an axial vector. It is directed always in a fixed direction (perpendicular to the plane of rotation either outward or inward), if the sense of rotate remain same.
