Multiple Choice

A small solid sphere is released from rest at the top of an inclined plane as shown. The sphere rolls down without slipping and reaches the bottom of the plane. How would the angular momentum of the sphere at the bottom of the plane change if the coefficient of static friction between the sphere and the plane were increased?

• It would decrease because the force of friction would be greater.

• It would decrease because the net torque would be larger.

• It would increase because the angular acceleration would increase.

• It would increase because the linear acceleration would increase.

• It would remain the same because the net torque would remain the same.
