A particle is moving uniformly along a straight line as shown in the figure. During the motion of the particle from A to B, the angular momentum of the particle about 'O'

A

remains constant

B

increases

C

first increases then decreases

D

decreases.

Text Solution

Verified by Experts

The correct Answer is:
A
(a): Angular momentum = `vecr xx vecp`
Here `vecr` and `vecp` are constant so angular momentum is constant.
