Question

find momentum of inertia of a solid sphere about its diameter if MI of solid sphere about tangent to the sphereis 7/5 MR2 where M is mass of the sphere and R radius of sphere​

Answer 1

According to the theorem of parallel axes, the moment of inertia of a body about any axis is equal to the sum of the moment of inertia of the body about a parallel axis passing through its centre of mass and the product of its mass and the square of the distance between the two parallel axes.

7/5MR2= MR2+ I

I=2/5MR2
