Class 11PhysicsFluid Mechanics and Surface TensionBuoyancy, Archimedes' Principle and Laws of Floatation
EasyState Archimedes' principle.
(N/A) Archimedes' principle states that when a body is partially or fully immersed in a fluid,it experiences an upward buoyant force equal to the weight of the fluid displaced by the body.
Mathematically,the buoyant force $F_B$ is given by $F_B = V \rho g$,where $V$ is the volume of the displaced fluid,$\rho$ is the density of the fluid,and $g$ is the acceleration due to gravity.
