A mass m is moving with a constant velocity along a line parallel to the x-axis, away from the origin. Its angular momentum with respect to the origin.

A

is zero

B

remains constant

C

goes on increasing

D

goes on decreases

Text Solution

Verified by Experts

The correct Answer is:
B
Angular momentum of mass m moving with constant velocity about origin is

L=moment `xx` perpendicular distance of line of action of momentum from origin, `L = mv xx y`
In the given condition, mvy is a constant. Therefore, angular momentum is constant.
