A concrete slab with a volume of 0.5m3 is in the water. What is the buoyancy force?

V = 0.5 m ^ 3.
ρ = 1000 kg / m ^ 3.
g = 9.8 m / s ^ 2.
Farkh -?
The buoyancy force of Archimedes is determined by the formula: Farch = ρ * g * V.
Where ρ is the density of the fluid in which the body is immersed, g is the acceleration of gravity, V is the volume of the immersed part of the body in the fluid.
Farch = 1000 kg / m ^ 3 * 9.8 m / s ^ 2 * 0.5 m ^ 3 = 4900 N.
Answer: the buoyancy force of Archimedes Farch = 4900 N acts on a concrete slab under water.
