State the law of floatation.

(N/A) The law of floatation states that a body will float in a liquid if the weight of the liquid displaced by the submerged part of the body is equal to the total weight of the body.
Mathematically, for a body of mass $M$ floating in a liquid of density $\rho$, the condition is:
$Weight \ of \ the \ body = Weight \ of \ the \ displaced \ liquid$
$Mg = V_{submerged} \rho g$
Where $V_{submerged}$ is the volume of the body submerged in the liquid.
