Floatation-
When a body of density is immersed in a liquid of density
,
Then the body will float if the buoyant force on the body is equal to the weight of the fluid displaced by the body. This means the body is in equilibrium.
If the density of the body is equal to that of liquid i.e
Then the Weight of the body will be equal to upthrust.
And the body will float but the body will fully be submerged in liquid.
If the density of the body is less than that of liquid
Then the Weight of the body will be less than upthrust.
And the body will float but the body will partially be immersed in liquid.
If the density of the body is greater than that of liquid
Then the Weight of the body will be greater than upthrust So the body will sink.
