PhysicsSystems of Particles and Rotational MotionMHT CET

A raw egg and a hard boiled egg are made to spin on a table with the same angular speed about the same axis. The ratio of the moment of inertia of raw egg and that of boiled egg about a central axis is

Answer: (C)

Solution

The contents of a raw egg are liquid and do not rotate rigidly with the shell, so the two eggs behave differently when spun: the raw egg's moment of inertia is
