Question

How do buoyant forces change with depth?

Answer 1

Normally does not vary with depth, unless the object is compressible, or density of fluid varies with deoth

Explanation:

Buoyancy or buoyant force is proportional to object's volume and density of the fluid in which the object floats.

`B prop rho *V`

So with depth, density may change, or the volums of the object will change when it gets compressed due to the higher pressure at greater depth.
