Archimedes Principle
Archimedes Principle
Statement: When an object is fully or partially immersed in a liquid, it experiences a buoyant force or upthrust which is equal to the weight of liquid displaced by the object, i.e. Buoyant force or upthrust acting on an object = Weight of liquid displaced by an object
Even gases like air, exert an upward force or buoyant force on the objects placed in them. It is buoyant force or upthrust due to displaced air which makes a balloon rise in air.
Applications of Archimedes Principle:
Archimedes principle is used in:
Illustration: If an iron object is immersed in water, it displaces 8 kg of water. How much is the buoyant force acting on the iron object in newton? ( Given, g = 10 )
