Question

the moment of inertia of a solid sphere about a tangent whose mass is 10kg and radius 10cm

​

Answer 1

The moment of inertia of a solid sphere about a tangent whose mass is 10 kg and radius 10 cm  is "400 kg$cm^{2}$".

Explanation:

Given,

Mass(M) = 10kg and Radius(R) = 10 cm

Find the moment of inertia of a solid sphere = ?

We know that,

The moment of inertia of a solid sphere = $\dfrac{2}{5}$ ×M$R^{2}$

=  $\dfrac{2}{5}$ × 10 × $10^{2}$

= 400 kg$cm^{2}$

Hence, the moment of inertia of a solid sphere about a tangent whose mass is 10 kg and radius 10 cm  is "400 kg$cm^{2}$".
