    Let I1 an I2 be the moments of inertia of two bodies of identical geometrical shape, the first made of aluminium and the second of iron.
    (a) I1 < I2
    (b) I1 = I2
    (c) I1 > I2
    (d) relation between I1 and I2 depends on the actual shapes of the bodies.
    digAnsr:   a
    Ans : (a) I1 < I2
    In the given case, we have:
    MOI `` \propto `` Density
    The density of iron is more; therefore, I2 will be greater.
