Experimental verification of Archimedes' principle
Measure the volume of water displaced. Let it be V.
Weight of water displaced by solid = Vpg
Therefore,
W1-W2 = Vpg
Weigh the object in air using a spring balance and note the reading W1.
Hence, This verifies Archimedes' principle.
Fill the measuring cylinder with water till some level.
Immerse the object into the water in the measuring cylinder. Note the weight, W2 from the spring balance
Experimental verification
Loss of weight in solid when immersed in water = W1-W2
Apparatus: Spring balance, measuring cylinder, any irregular small object, thread, water.
Archimedes' principle
When a body is immersed fully or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by it.
