The upthrust force given on any object by any liquid is called Buoyancy.
An object floats on the surface of liquid when its density is lesser than that of the liquid and in that case the buoyant force can fully act on it.
An object sinks when its density is greater than that of the liquid, in that case the gravity can fully act on its density is more than the buoyant force and helps it to sink.
hope it helps u
