Question

Define Archimedes principle. How can it be experimentally verified?

Answer 1

Archimedes' Principle states that, A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.
Archimedes principle also states that, When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.
It can be verified experimentally by the following experiment.
Take a tumbler of water and place the tumbler in a beaker of known weight. Take a small stone and measure the weight of the stone by a spring balance. Note down this weight. Now, dip the stone completely in the tumbler slowly. Water from the tumbler will flow down to the beaker. Gently take away the tumbler. Measure the weight of the beaker. You can find that the increased weight of the beaker is same as th weight of the stone.
