The substance whose density is less than the density of water tends to float on water. The density of dead human body is less than that of density of water so dead body floats on water as the body is able to displace the water equivalent to its weight. The body also floats because of the air presentRead more
When the bucket of water is inside the well then upthrust i.e. buyoant force in upward direction so it becomes easy for us to pull the bucket of water in well. But out of the well no such force is acting in bucket so it becomes difficult.
