Question

Of the two eggs which have identical sizes, shapes and weights, one is raw and other is boiled. The ratio between the moment of inertia of the raw to the boiled egg about central axis is :

• A. $=1$
• B. > 1
• C. < 1
• D. not comparable

Answer 1

Answer: (B)

> 1

In half boild egg mass in concentrated near the axis.
where as the mass of raw egg is distributed all over the egg,
$\therefore$ Moment of inertia of raw egg is greater than the half boiled egg.
Hence, ratio of their moment of inertia is greater than 1.
