Question

Why a man will be found lighter when weighted in air than in vacuum?

Answer 1

Answer:

The simple reason is that air is made of many constituents. When a body is weighed in air the buoyant force of the air will reduce its weight. Contrarily, in vacuum there would be no such force, thus the weight of a body would be more, though negligible.

Answer 2

Answer:

Yes, because of Density of the air we learn that buoyant force is always acting on the body by it volume. Therefore, in vacuum there is no air, there is no buoyant force acting on body so the body is fell more heavier than air. For egs :-in water.

Here, body means man.
