Upthrust Question: 2 Conditions for Independence on Depth

[Zaimeen]

I found this question about upthrust

"give two conditions for the upthrust of a body to be independent upon the depth of imersion"

Any ideas?

 

[Gokul43201]

I have only one (and another, which is almost always assumed). What about you ?

How is the upthrust/buoyant force calculated ? What is the expression for it ?

 

[Zaimeen]

Upthrust is calculated as follows

U = \rho g V, where \rho is the density of the fluid,
g is the acceleration due to gravity and V the volume of the immersed body.

So, what are the conditions for the upthrust to be independent of the depth of immersion?

So Gokul43201 , any ideas?
