Rotational Motion Question 5

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

[AIEEE 2002]

Options:

A) mvL

B) mvl

C) mvr

D) 0

Show Answer

Answer:

Correct Answer: B

Solution:

  • [b] The angular momentum of a body of constant mass and constant velocity depends upon the perpendicular distance from a fixed point (origin). Angular momentum of particle about 0 $ L=m(r\times v) $ $ | L |=mv\sin \theta =mv(r\sin \theta )=mvl $
