A granite slab with dimensions 3.5 * 0.3 * 0.2 is immersed in water. Calculate the Archimedean force.

Initial data: the dimensions of the granite slab are 3.5 x 0.3 x 0.2 m.

Reference values: ρw (density of water in which the granite slab was immersed) = 2600 kg / m3; g (acceleration due to gravity) ≈ 10 m / s2.

1) Determine the volume of the granite slab: V = a * b * c = 3.5 * 0.3 * 0.2 = 0.21 m3.

2) Calculate the force of Archimedes: Fa = ρw * g * V = 1000 * 10 * 0.21 = 2100 N.

Answer: A buoyancy force of 2100 N acts on a granite slab in water.
