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?



Answer :

MathPhys

Answer:

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

Explanation:

Since the sphere rolls without slipping, the friction force is static, so no work is done by the friction force. Therefore, the sphere's final angular velocity is independent of the friction coefficient. It is only a function of the height of the plane, the acceleration due to gravity, and the radius of the sphere.
