Moment of Inertia and its Significance :: Discussion

2.	A particles undergoes uniform circular motion. About which point on the plane of the circle, will the angular momentum of the particles remain conserved?
	A.	Centre of the circle
	B.	On the circumference of the circle
	C.	Inside the circle
	D.	Outside the circle

	Answer: Option A


	Explanation:
	In uniform circular motion, centripetal force acts towards the centre. Torque due to such a force about the centre is zero. Hence the angular momentum is conserved about the centre of the circle.
