For a sphere made out of a certain material, the moment of inertia of the sphere is proportional to [radius of the sphere = $R$ ]

Options:

Answer:

Solution:

Moment of inertia of a solid sphere is $\frac{2}{5} m R^{2}$

$I = \frac{2}{5} m R^{2}$

$I = \frac{2}{5} V ρ R^{2}$

$I = \frac{2}{5} \times \frac{4}{3} π R^{3} ρ R^{2}$

$I = \frac{8}{15} π ρ R^{5}$

$I \propto R^{5}$
