A bar, the volume of which is 4 dm3, was immersed in kerosene, the density of which was. Calculate the magnitude of the buoyancy force acting on a body immersed in kerosene.

To find the magnitude of the buoyancy force acting on the presented bar, we use the formula: Fa = ρker * g * V.

Data: ρker – kerosene density (ρker = 802 … 840 kg / m3; we take ρker = 821 kg / m3); g – acceleration of gravity (g = 9.81 m / s2); V is the volume of the presented bar (V = 4 dm3 = 4 * 10-3 m3).

Calculation: Fa = ρker * g * V = 821 * 9.81 * 4 * 10-3 ≈ 32.2 N.

Answer: The buoyancy force acting on the presented bar is 32.2 N.
