Calculate the Archimedean force acting on a 200 cm3 block of wood immersed in machine oil.

Calculate the Archimedean force acting on a 200 cm3 block of wood immersed in machine oil. Density of wood is 700 kg / m3, of machine oil – 900 kg / m3.

In this problem, we apply the formula of the Archimedes Force F (a) = p * g * V, but first we translate the volume into SI, V = 200 cm ^ 3 = 0.0002 m ^ 3 and then we already find the force itself, knowing the volume of the immersed part , g = 9.8 and the density of the liquid (by condition). F (a) = 900 * 9.8 * 0.0002 = 1.764 Newtons.
