MCQ

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

✓
Centre of the circle
B
On the circumference of the circle
C
Inside the circle
D
Outside the circle

✓

Answer

Correct option: A.

Centre of the circle

a
The net force acting on a particle undergoing uniform circular motion is centripetal force which always passes through the centre of the circle. The torque due to this

force about the centre si zero, therfore, $L$ is conserved about $O.$
