Solution

  1. 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 downward.
  2. 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.
