| **Calculate the buoyancy for a marble slab submerged in water. The volume of the slab is 2m3 of river water = 1000kg \ m3**

The buoyancy force of Archimedes will act on a marble slab in water, which is equal to:

Fa = ρ * g * V, where ρ is the density of water (ρ = 1000 kg / m ^ 3), g is the acceleration of gravity (we take g = 9.8 m / s ^ 2), V is the volume of the submerged part of the marble slab (V = 2 m ^ 3).

Let’s calculate the buoyancy force of Archimedes:

Fa = ρ * g * V = 1000 * 9.8 * 2 = 19600 N = 19.6 kN.

Answer: The buoyancy force of Archimedes is 19.6 kN.
