does buoyant force increase with depth

Buoyant forces= weight of fluid displaced by the body.Weight of liquid displaced depends upon the density of the fluid,”g” and volume of the body immersed in the fluid .Now in case of ideal , incompressible fluid density remains constant and also g as well as density of the body is also constant so buoyant forces will remain constant.But if fluid is compressible density will vary with depth … The bottom of the object i.e. Key Terms
The reason is that the buoyant force is in fact due to the difference in pressure above and below an object.


You can calculate the buoyancy force either directly by computing the force exerted on each of the object’s surfaces, or indirectly by finding the weight of the displaced fluid.

This is because water is incompressible.

So with increasing depth there is a small increase in the potential buoyant force. Nope, the buoyant force does not change with depth.

The force on the bottom pushes up and the force on the top pushes down (since force is normal to the surface). The buoyant force is equal to the weight of fluid displaced.

A typical situation: The pressure on the bottom of an object is greater than the top (since pressure increases with depth). The buoyancy of an object submerged in water does not normally change substantially with depth, but there are caveats to this answer. The buoyancy force always points upwards because the pressure of a fluid increases with depth. However if you are diving in a submarine it is more likely that your sub will compress more than the water will, so your buoyancy will go down with increasing depth even as the water becomes marginally denser. the part which is at a greater depth, will also feel a greater pressue, and so the difference in pressure causes an upward force on the object called the buoyant force. there is no term that is proportional to depth, which shows that the buoyant force does not get smaller as you sink.
