Buoyant Force/ Upthrust:
Factors Affecting Buoyant Force:
There are two factors in which e magnitude of buoyant force acting on an object immersed in a liquid depends:
The buoyant force exerted by a liquid depends on the volume of the solid object immersed in the liquid. The upward buoyant force increases with the increase in the volume of solid object immersed inside the liquid. The magnitude of buoyant force acting on a solid object does not depend on the nature of the solid object.
The buoyant force exerted by a liquid depends on the density of the liquid in which the object is immersed. An object whose density is greater than that of the fluid in which it is submerged tends to sink. Even a very heavy material like an iron block floats in mercury because mercury exerts a very high buoyant force on iron block due to its very high density. Thus, if the object is either less dense than the liquid or is shaped appropriately (as in a boat), the force can keep the object afloat.
