Mass of a body is 10 kg at the surface of the earth. At what depth does its mass reduce to 5 kg?

Solution

Mass of the body is proportional to the quantity of matter contained in the body and independent of the acceleration due to gravity.
Therefore, the mass of the body does not change with depth and hence it will not be 5 kg anywhere.
