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

A

one

B

greater than one

C

less than one

D

not comparable

Text Solution

Verified by Experts

The correct Answer is:
B

A raw egg behaves like a spherical shell and a half boiled egg behaves like a solid sphere.
`therefore" "(l_(r))/(l_(s))=(2//3mr^(2))/(2//5mr^(2))=(5)/(3)gt1`
