The mass and gravity acting on a person, if he drinks 0.2 liters of water, will increase accordingly by …

| Given:
V = 0.2 liters = 0.2 dm3 (cubic decimeters) – the volume of water that a person drank;
ro = 1000 kg / m3 (kilogram per cubic meter) – density of water.
It is required to determine how much the mass and gravity acting on a person will increase after he drinks water.
Let’s convert the units of measurement of volume to the SI system:
V = 0.2 dm3 = 0.2 * 10-3 m3 (cubic meter).
Then, the mass of water you drink will be equal to:
m = ro * V = 1000 * 0.2 * 10-3 = 0.2 kilograms.
The force of gravity will increase by an amount equal to:
F = m * g (where g = 9.8 Newton / kilogram);
F = 0.2 * 9.8 = 1.96 Newton.
Answer: the mass of a person will increase by 0.2 kilograms, the force of gravity – by 1.96 Newton
