A circular disc A of radius r is made from an iron plate of thickness t and another circular disc B of radius 4r is made from an iron plate of thickness `t//4`. The relation between the moments of inertia `I_(A)` and `I_(B)` is (about an axis passing through centre and perpendicular to the disc)

`I_(A) gt I_(B)`

`I_(A)=I_(B)`

`I_(A) lt I_(B)`

depends on the actual values of t and r.
