Question

For the same total mass which of the following will have the largest moment of inertia about an axis passing through its center of mass and perpendicular to the plane of the body

Answer 1

Hey mate,
You forgot to add options-
ring, disc, square, etc.

● Answer- ring

● Explaination-
Consider,

- For a ring of radius r
Ir = mr^2

- For a disc of radius r
Id = 1/2 mr^2

- For a square of side r
Is = 2/3 mr^2

From these results we can say that-
Ir > Id > Is

Hope this helps you...
