A particle of mass m moves along line PC with velocity v as shown in the figure. What is the angular momentum of the particle about O?

A

mvL

B

mvl

C

mvr

D

zero

Text Solution

Verified by Experts

The correct Answer is:
B
Angular momentum of particle about O,
`L=m(rxxv)`
`|L|=mr v sin theta=mv(r sin theta)=mvl`
