Question

A solid sphere of mass 6kg and radius 2m is rotating about it's diameter . calculate the radius of gyration of the sphere​

Answer 1

The radius of gyration of the sphere​ is 1.26.

Explanation:

Given that,

Mass of the solid sphere, m = 6 kg

radius of the solid sphere, R = 2 m

We need to find the radius of gyration of the sphere​. For a solid sphere that is rotating about diameter of the sphere, the radius of gyration is given by :

$K=\sqrt{\dfrac{2}{5}}R$

$K=\sqrt{\dfrac{2}{5}}\times 2$

K = 1.26

So, the radius of gyration of the sphere​ is 1.26. Hence, this is the required solution.
