Archimedes' Principle
According to Archimedes principle, mass of an object in water would be less than mass of an object in air.So imagine an object of 5 kg and weight of a vessel containing water as 100 kg. The total weight is 105 kg. Now place a weighing machine under the water vessel and immerse the object into the water. Now can I except the weighing machine shows the weight less than 105 kg?
sudeeb
- Dec 20th, 2010
Acc to A.P -- Weight of the water displaced is equal to the weight of the body. So the weighing scale indicate the same weight 105 kg. but when we lift the body we will feel low weight due to the upward bouncy force. and body float/sink depend upon the bouncy force and metacentre.
