Determine the force of Archimedes, which acts on a 10 cm3 metal cylinder immersed in oil.

Given:

V = 10 cm3 (cubic centimeters) – the volume of a metal cylinder immersed in oil;

ro = 900 kg / m3 (kilogram per cubic meter) is the density of the oil.

It is required to determine A (Newton) – buoyancy (Archimedean) force acting on the cylinder.

Let’s translate the units of measurement of volume in the SI system:

V = 10 cm3 = 10 * 10-6 = 10-5 m3.

Then, to determine the buoyancy force, you need to use the following formula:

A = ro * V * g, where g = 10 Newton / kilogram (approximate value);

A = 900 * 10-5 * 10;

A = 900 * 10-4 = 9 * 10-2 = 0.09 Newton.

Answer: an Archimedean force equal to 0.09 Newton will act on a metal cylinder immersed in oil.
