Question
Off two eggs which identical sizes, shapes and weights, one is raw and the other is half - billed. The ratio between the moment of inertia of the raw egg and that of the half-boiled egg about a central axis is : -
Options
A.one
B.greater than one
C.less than one
D.incomparable
Solution
Raw egg acts as a ring (because material lies on the perimeter) and half boiled egg be haves as a disc. M.I of ring > M.I of disc.
