Question

Angular momentum of a particle is conserved when F = 0.

Answer 1

True

Step-by-step explanation:

As we know that the torque can be written as,

`\tau=r* F`

According to the question total forece,
`F=0`

This total null force will make the torque zero.

And torque is related to angular momentum as,

`\tau=(dL)/(dt)`

Here, L is angular momentum.

Now,

`(dL)/(dt)-=0\\ L=constant`

Therefore, the angular momentum of a particle is conserved when the total force F=0.
