Question

The moment of inertia of a solid sphere about a tangential axis is

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

Answer 1

The correct option is B $\frac{2}{5}M{R}^2$

The momentum of inertia of a solid sphere about a tangential axis is $\frac{2}{5}M{R}^2$

Hence,

option $B$ is correct answer.
