JEE Main Physics question

About which point is the angular momentum of a particle in uniform circular motion conserved? **[IIT JEE 2003]**

(A)Any point on the circumference
(B)The centre of the circleCorrect
(C)Any point outside the circle
(D)It is never conserved

Answer: (B)

Solution

In uniform circular motion the only force is centripetal, always directed toward the centre. Its torque about the centre is zero (force passes through the reference point),
