What is the buoyancy force acting on a silver body thrown into the river if its volume is 1.8m3?

These tasks: V (volume of a silver body thrown into the river) = 1.8 m3.

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

The buoyancy force acting on the silver body in the river is determined by the formula: Fa = ρw * g * V.

Let’s make a calculation: Fa = 1000 * 10 * 1.8 = 18 * 10 ^ 3 N (18 kN).

Answer: A buoyant force of 18 kN acts on the silver body.
