Solution: Two spheres, A and B, have the same mass and radius. However, sphere B is made of a dense core and a less dense shell around it. How does the moment of inertia of sphere A about its center of mass com

Two spheres, A and B, have the same mass and radius. However, sphere B is made of a dense core and a less dense shell around it. How does the moment of inertia of sphere A about its center of mass compare to the moment of inertia of sphere B about its center of mass?

Ia. I_{A} > I _{B}

Ib. I_{A} < I _{B}

Ic. I_{A} = I _{B}

If the two spheres are rolled down an incline from the same height simultaneously,

IIa. sphere A reaches the bottom first.

IIb. sphere B reaches the bottom first.

IIc. spheres A and B reach the bottom simultaneously.
