Materials required:-
----> Piece of stone,Rubber string(or)Spring balance,Beaker filled with water.
*Procedure:-
(1)Take a piece of stone and tie it to one end of a rubber string or a spring balance.
(2)Suspend the stone holding the balance.
(3)Note the elongation of the string or the reading on the spring balance due to weight of the stone.
(4)Now,Slowly dip the stone in the water in a container.
(5)Observe what happens.
Observations:-
(1)You find that the elongation of the string decreases as the stone is gradually immersed in the water.
(2)No further change is observed once'when the stone fully gets immersed into the water.
Inference:-
(1)It is due to the buoyant force or upthrust exerted by water.This was found out by Archimedes and hence named Archimedes'Principle.
