प्रश्न
How does the density ρs of a substance determine whether a solid piece of that substance will float or sink in a given liquid ρL?
उत्तर
The body will float if its density is less than or equal to the density of the liquid ρs ≤ ρL.
The body will sink if its density is greater than the density of the liquid ρs > ρL.
