A football and a stone has same mass i) both have same inertia ii. both have same momentum iii) both have different inertia iv. both have different momentum

The moment of inertia of solid sphere is defined as, the moment of inertia is equal to the product of mass and radius. Here, football and stone as a solid sphere.

I = MR2

We need to calculate the moment of inertia of football

Using formula of moment of inertia of a solid sphere

I = 2/3MR2

Put the value into the formula I = 2/3mr2

If a football and a stone has same mass then the moment of inertia will be same.

Hence, both have same inertia
