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

In U.C.M., only centripetal force facts on the particle. The torque of the centripetal force about the centre is zero. Hence the angular momentum about the centre is conserved.
