Why does a solid sphere have a smaller moment of inertia than a hollow cylinder of the same mass and radius, about an axis passing through their axes of symmetry?

Options

  1. AThe mass distribution of the solid sphere is more concentrated towards its center compared to the hollow cylinder.
  2. BThe solid sphere has a smaller radius than the hollow cylinder, resulting in a smaller moment of inertia.
  3. CThe material used to make the solid sphere is less dense compared to the material used for the hollow cylinder, affecting the moment of inertia.
  4. DThe solid sphere has a larger mass than the hollow cylinder, contributing to a smaller moment of inertia.

Correct answer

A. The mass distribution of the solid sphere is more concentrated towards its center compared to the hollow cylinder.

Step-by-step solution

Correct Option is : (A)
The mass distribution of the solid sphere is more concentrated towards its center compared to the hollow cylinder.
