MCQ

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

A
Angular momentum remains constant
B
Acceleration ($\vec a$) is towards the center
C
Particle moves in a spiral path with decreasing radius

Answer

Correct option: D.

The direction of angular momentum remains constant

d
(d) Angular momentum is a axial vector. It is directed always in a fix direction (perpendicular to the plane of rotation either outward or inward), if the sense of rotation remain same.
