Question

It is easier to lift a heavy stone under waterthan in air explain

Answer 1

because of the density of water in comparison to air is to high.

Answer 2

It is easier to lift a heavy stone under water than in air because in water, it experiences an upward buoyant force which balances the actual weight of the stone acting downwards. Thus, due to upthrust there is an apparent loss in the weight of the heavy stone, which makes it lighter in water, and hence easy to lift.
