Question

A solid body of mass 150 g and volume $250c{m}^3$ is put in water . Find the density of the body .Will following substance float or sink if the density of water is $1g^{-}3$?

• A. Float,0.6 gm/cm3
• B. Sink,0.6 gm/cm3
• C. Sink,1 gm/cm3
• D. Float ,0.8 gm/cm3

Answer 1

The correct option is A Float,0.6 gm/cm3

The substance will float if its density is less than water and will sink if its greater.

so, density of solid body is d = mass/volume

or d = 150/250 = 0.6 $g/c{m}^3$ which is less than the density of water (1 gm/3).

So, the solid body will float on water.
