Two circular discs A and B of equal mass...

Two circular discs `A` and `B` of equal masses and thicknesses. But are made of metals with densities `d_A and d_B (d_A gt d_B)`. If their moments of inertia about an axis passing through the centre and normal to the circular faces be `I_A and I_B`, then.

`I_(1) gt I_(2)`

`I_(1) gt gt I_(2)`

`I_(1) lt I_(2)`

`I_(1)=I_(2)`
