Question

How can you differentiate the boiled egg from a raw egg by using the Newton's
laws?
a) When we rotate both eggs the boiled one will come to rest first and the raw egg
as consists of liquid, due to inertia it rotates further
b) When we rotate both eggs the boiled one will rotate for longer period of time
then the raw egg.
c) We cannot differentiate boiled egg from raw egg by using Newton's laws.
d) All the above options are correct.

Answer 1

Answer:

a. inside its shell, a hard-boiled egg is solid whereas a raw egg is fluid.

When you spin the raw egg, its centre of gravity (or balance point) changes as the fluid inside the egg moves around. This results in a wobbling motion in order to achieve balance.

When the hardboiled egg is spun, the solid centre has a fixed centre of gravity, causing it to move at the same time as the shell. This results in a smooth, balanced spin.
