Question

Of two identical raw and half boiled eggs, the ratio between moment of inertia of the raw egg to that of half boiled egg about main axis is (A) one (B) greater than one (C) less than one (D) not comparable.

MOI depends upon distribution of mass i.e.

I = M k^{2}

Yoke of raw egg moves to periphery on rotation so it will have more moment of inertia as compared to half boiled egg. The half boiled egg behaves as solid spherical body.

greater than one

less than one
