Question

A boiled egg and a raw egg of same mass and size are made to rotate about their own axis. If $I_1$ and $I_2$ are moments of inertia of boiled egg and raw egg respectively, then:

• A. $I_1=I_2$
• B. $I_1>I_2$
• C. $I_1<I_2$
• D. $I_1=\sqrt{2}{I}_2$

Answer 1

Answer: (C)

$I_1<I_2$

$I_2>I_1$
Because mass in case of boiled egg is concentrated near the axis of rotation and mass of raw egg is concentrated at the surface away from the axis of rotation.
