Solution
Correct Answer:
m v r
Angular momentum (L) of a particle about a point is: L=r×p=r×(mv) For circular motion, the position vector r (from the center) is always perpendicular to the velocity vector v. The magnitude is: L=rmvsin90∘=mvr In terms of angular velocity: L=m(rω)r=mr2ω=Iω.
This easy difficulty physics question is from the chapter rotational motion, covering the topic of angular momentum. It appeared in the 2025 exam.
