A mass M moving with a constant velocity parallel to the X-axis. Its angular momentum with respect to the origin

A

is zero

B

remains constant

C

goes on increasing

D

goes on decreasing

Text Solution

Verified by Experts

The correct Answer is:
B
Angular momentum

`vecL=vecrxxvecp`
`L=` momentum `xx` perpendicular distance of line of action of momentum w.r.t point of rotation
`L=Mvxxy`
The quantities on the right side of the equation are not changing. Thus, magnitude is constant.
