A body immersed in a liquid is acted upon by an upward force called upthrust
Upthrust of the body depends on the volume of the body submerged in liquid and the liquid's density.
Multiply volume with (rho) 1000 and g to get the buoyant force.
Seawater is denser than river water. The upthrust due to seawater will be greater than that due to river water at the same level.
The property of a liquid to exert an upward force on an immersed body is called Buoyancy.
The upthrust on the body due to its submerged part is equal to its own weight. A body shall weigh more in a vacuum as no upthrust is acting on the body.
The large volume of the body means greater upthrust acting on it
A stone falls faster than a bunch of feathers
In Turpentine, an immersed body is acted upon by a minimum upthrust.
