Question

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

(a) centre of the circle

(b) on the circumference of the circle

(c) inside the circle

(d) outside the circle

Answer 1

The force will pass through the centre of the circle. Therefore, the angular momentum will remain conserved at the centre of the circle.

hence, your answer is (a) centre of the circle
