Question

What is archimedes principle? How can we find the relative density of a solid using it?

Answer 1

Answer:

Archimedes principle- a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.

The buoyant force on a submerged object is equal to the weight of the fluid displaced. This principle is useful for determining the volume and therefore the density of an irregularly shaped object by measuring its mass in air and its effective mass when submerged in water (density = 1 gram per cubic centimeter).
