A solid homogeneous sphere is moving on ...

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

A

total kinetic energy of the sphere is conserved.

B

angular momentum of the sphere about any point on the horizontal surface is conserved

C

only the rotational kinetic energy about the centre of mass is conserved

D

none of the above

Text Solution

Verified by Experts

Friction will act (due to sliding) but torque of friction about the mentioned point in the question will be zero. Hence, angular momentum will remain constant.
