Question

A raw egg and hard boiled are made to spin on a a table with the same angular speed about the same axis. The ratio of the time taken by the two to stop is

• A. Equal to one
• B. Less then one
• C. more than one
• D. Equal to two

Answer 1

The correct option is A Equal to one

Boiled egg rolls slower than a raw egg , because it has a higher moment of inertia than a raw egg . In order to conserve angular momentum , the angular velocity of the boiled egg decreases .

The hard boiled egg moves as if it was one solid unit. The raw egg has a solid shell but various types of fluids inside that can move independently of the shell. When you turn the egg to cause it to spin this rotating or turning force is called a torque.

How the boiled egg spins? The rotating force on the shell of the hard boiled egg spins the entire egg –shell and content because the content is solid and moves when the shell moves.This egg easily spins and spins longer than does the raw egg.
