A particle undergoes uniform circular motion. About which point on the plane of the circle, will the angular momentum of the particle remain conserved?

Options

A. Centre of the circle
B. On the circumference of the circle
C. Inside the circle
D. Outside the circle

Answer

A

Explanation

`|vecL|=mvr`

The direction `vecL` (about the centre) is perpendicular to the plane containing the circlar path. Both magnitude and direction of the angular momentum of the particle moving in a circular path about its centre `O` are constant.
