Plz and this ques
Dear Student
An object will float on the surface of water if its density is less than the density of the liquid it is placed into. A force called upthrust acts on all objects placed in a liquid. The weight of a floating object is exactly balanced by the upthrust.
An object sinks in water if its density is more than the density of the liquid. The weight of a sinking object is greater than the upthrust.

Both the phenomenon depends on the of the densities of the body and the liquid in which that body is placed .
