Question

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

Answer 1

Mass:
The mass of a body is the quantity of matter contained in it. The mass of a body is constant and does not change from place to place. The mass of a body cannot be zero.

Solution:

Gases (like air) even exert upward force (buoyant force) on the objects place in them.

When we stand on a weighing machine then the air exerts an upward force (buoyant force or upthrust) on our body and makes us slightly lighter then we actually are. So if a weighing machine shows our mass to be 42 kg then our actual mass will be slightly more than 42 kg.

Hence , our actual mass will be slightly more than 42 kg..

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.
