1.	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 circleB. on the circumference of the circle.C. inside the circleD. outside the circle.
Answer» Correct Answer - A (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, `vecL` is conserved about O.
