The gold will be heavier if we try to lift it..
Weight is the force acting on a body due to gravity..
In vacuum the weight of 1kg of cotton and 1kg of gold will be the same..
We know tat cotton is very much less denser than gold.. So 1kg cotton will take up much more volume than 1 kg of gold.
Buoyancy of air causes an upthrust on both gold and cotton.. This upthrust is directly proportional to the volume of air displaced.. So a higher upthrust will act on Cotton..
So the net force acting downwards on Cotton will be smaller..
So cotton will be easier to lift up..
