A solid body of mass 150 g and volume 250 `cm^3` is put in water. Will the body float or sink?

Answer» Here, mass of the body, `M=150g`
volume of the body, `V=250cm^3`
density of the body, `d=(M)/(V)=(150g)/(250cm^3))`
`=0.6(g)/(cm^3)`
Since the density of the body `(0.6(g)/(cm^3)`) is less than the density of water `(1(g)/(cm^3)`), the body will float on water.
