briefly explain the experimental verification of Archimedes principle
Answers
Loss of weight in solid when immersed in water = W1 - W2. ... It is found that W1 - W2 loss in weight of solid when immersed in water is equal to the weight of the water displaced by the body. This verifies Archimedes' principle

Answer:
Archimedes’ principle: The Archimedes’ principle states that if a body is immersed in a fluid, wholly or partly, then it loses its weight equal to the weight of fluid displaced by the immersed part of the body.
EXPERIMENTAL VERIFICATION OF ARCHIMEDES PRINCIPLE - DEFINITION
concept
Take a stone of known volume with density greater than water and hang it with a spring weighing balance. Record the mass m (=W1)
and volume V. Now lower the system of stone and weighing balance into water slowly such that the stone is completely immersed in water (weighing machine is not immersed). Note the new reading of the weighing machine m2 (=W2). It is observed that m2<m suggesting that existence of an upward force.
Calculate Upthrust = Difference in weights, ΔW=(m−m2 )g
Calculate weight of water displaced, Ww
=ρwVg
It is observed that ΔW=Ww
