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. at the centre of the circle
B. on the circumference of the circle
C. inside the circle
D. outside the circle

Answer

A

Explanation

We known `(dvecL)/(dt)=tau`
In uniform circular motion the torque about the centre of circle is ZERO. Therefore, L = constant.
