Answer: Hoop

Explanation:

The general formula for rotational inertia (I) is given as:

I = mr², where:

  • m is the mass
  • r is the radius, or the distance of the concentration of mass from the center

Since there is less concentration of mass from the center for the hoop, the r value is going to be bigger.

There is more mass located near the center of the solid disk, so it will have a smaller r value and therefore less rotational inertia.

Therefore, the hoop has a larger rotational inertia.
