Conditions for stable equilibrium for floating body

The meta center must always be higher than the center gravity of the body.


The line joining the center of gravity of the body and center of floatation should be vertical.


We know density is mass per unit volume. Its S.I unit is kg/m3 and relative density is density of material per density of water at four degrees Celsius.


Relative density is measured by Hydrometer.

•    The density of sea water is more than that of normal water. That is why it is easier to swim in sea water.

•    When ice floats in water, its 1/10th the part remain outside the water.

•    If ice floating in water in a vessel melts, the level of water in the vessel does not change.

•    Purity of milk is measured by lactometer.
