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

True

Explanation:

As we know that the torque can be written as,

According to the question total forece,

This total null force will make the torque zero.

And torque is related to angular momentum as,

Here, L is angular momentum.

Now,

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