Why is the net torque is around zero when an ice skater does a spin?
1
Because there is high friction between skates and ice.
2
Because the friction is far from the pivot point
3
Because the friction is varying with the angular momentum
4
Because the low friction between skates and ice and is exerted near the pivot point
