Answer 2

Answer:

Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero. ... If the change in angular momentum ΔL is zero, then the angular momentum is constant; therefore, →L=constant L → = constant (when net τ=0).
