A solid homogeneous sphere is moving on a rough horizontal surface partly rolling and partly sliding. During this kind of motion of the sphere

View answer and explanation

Correct option: B

The angular momentum of the sphere about the point of contact with the plane is conserved

Option B (The angular momentum of the sphere about the point of contact with the plane is conserved) is correct because there is no net torque about the point of contact.
