The volume of the body is 0.002 m3, and its weight in the air is 16N. Will it sink in kerosene?
| February 16, 2021 | education
Let’s find the mass of the body in the air:
M = 16N / 9.81N / kg ≈ 1.63kg.
Let’s determine the density of the body:
ρ = M / V = 1.63 / 0.002 = 815kg / m³.
We see that 815> 800.
Even excluding the density of air, the density of the body exceeds the density of kerosene. In fact, according to Archimedes’ law, the density of a body is greater than the obtained number by the value of the density of air.
Answer: This body will drown in kerosene.
