Answer 2

Answer:

Even gases like air exert an upward force on the objects placed in them. Now, when we stand on a weighting machine, then the air exerts an upward force on our body and makes us slightly lighter than we actually are. So, if weoghting machine shows our mass to be 42 kg, then our actual mass will be slightly more than 42 kg.
