Expert Answer
disc-A and disc-B has same mass. Density of disc-A is ρ1 and density of disc-B is ρ2 .
Since it is given that ρ1> ρ2 , then volume of disc-B is greater than volume of disc-A.
But both disc has same thickness. Hence cross section area of disc-B is more or radius of disc-B is more.
For same mass of two circular discs, moment of inertia is greater for the disc that has greater radius.
Hence disc-B has greater moment of inertia compare to disc-A
