A

is zero

B

remains constant

C

goes on increasing

D

goes on decreasing

Text Solution

Verified by Experts

The correct Answer is:
B
Consider the diagram

As, the particle goes with constant linear velocity, the perpendicular distance of velocity vector from the axis is constant. So, angular momentum `mvr sin theta` is constant.
