Question

The moment of inertia of a sphere of 100kg mass and a diameter of 100cm is?

Answer 1

The moment of inertia is `=10kgm^2`

Explanation:

The moment of inertia of a sphere is

`I=2/5mr^2`

The mass is `m=100kg`

The radius is `r=d/2=0.5m`

The moment of inertia is

`I=2/5*100*0.5^2=10kgm^2`
