Given: V (the volume of the taken bar) = 20 cm3 (in the SI system V = 20 * 10-6 m3).

Reference values: g (acceleration due to gravity) ≈ 10 m / s2; according to the condition ρw (water density) = 1000 kg / m3.

To determine the required buoyancy force acting on a given bar, we will use the formula: Fa = ρw * g * V.

Calculation: Fa = 1000 * 10 * 20 * 10-6 = 0.2 N.

Answer: The buoyancy force is 0.2 N.
