On a body with a volume of 5 cubic decimeters, when fully immersed in a liquid, a buoyant force of 50 Newtons acts what kind of liquid it is.
Farch = 50 N.
V = 5 dm3 = 0.005 m3.
g = 10 N / kg.
ρzh -?
To determine a liquid, it is necessary to find its density ρl and, according to the table of the density of substances, see what kind of liquid it will be. We express the density of the liquid ρzh from the formula for determining the Archimedes force Farch: Farch = ρzh * V * g.
ρzh = Farch / V * g.
ρw = 50 N / = 0.005 m3 * 10 N / kg = 1000 kg / m3.
According to the density table of substances, fresh water corresponds to this density value.
Answer: the body is completely immersed in fresh water.
