Question

the moment of inertia of different spheres all of same density of radius R about an Axis passing through the centre is proportional to​

Answer 1

Answer:

we know that

moment of Inertia of hallow sphere =

3

2

mR

2

and, moment of

Inertia of sold sphere =

5

2

mR

2

where

m→ mass of sphere

R→ radius of sphere

Therefore,

moment of inertia of sphere is proportional to R
