A Uniform Sphere of Radius R and Mass M Rotates $\frac{2}{5} M R^{2}$

question 6

Multiple Choice

A uniform sphere of radius R and mass M rotates freely about a horizontal axis that is tangent to an equatorial plane of the sphere, as shown below. The moment of inertia of the sphere about this axis is:

• A) \(\frac{2}{5} M R^{2}\) .
• B) \(\frac{2}{3} M R^{2}\) .
• C) \(\frac{5}{7} M R^{2}\) .
• D) \(\frac{7}{5} M R^{2}\) .
• E) \(\frac{3}{2} M R^{2}\) .
