(A) When you stand on a weighing machine,the machine measures the normal force exerted by your body on it.Due to the presence of air,a buoyant force acts on your body in the upward direction.This buoyant force reduces the net downward force exerted by your body on the weighing machine.Therefore,the reading shown by the weighing machine is slightly less than your actual mass.Thus,your actual mass is more than $42\, kg$.

You find your mass to be $42\, kg$ on a weighing machine. Is your mass more or less than $42\, kg$?
