Question

hello guys:-
what do you know about law of conservation of angular momentum?

Answer 1

When the net external torque acting on a system about a given axis is zero, then the total angular moment um of the system about that axis remains constant

Answer 2

♠ ANSWER :

According to the law of conservation of Angular momentum, if total external moment of force on a system is zero, then the vector τ of a system remains conserved.

d τ / d t = 0.

Vector τ = 0.
