A cork of density 0.18gm/cc floats in liquid of density 1.44 gm/cc with 20cc of volume inside the liquid. Find the mass and volume of the cork.
Density of the cork, = 0.18 gm/cc
Density of liquid, = 1.44 gm / cc
Volume of liquid, V = 20 cc
Now, according to the law of floatation,
Weight of cork = Weight of liquid displaced by cork.
Therefore mass of the cork is given by,
Volume of the cork,
