Upthrust question

  1. Jan 8, 2005 #1
    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?

    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 ?

    Upthrust is calculated as follows

    [tex] U = \rho g V [/tex], where [tex] \rho [/tex] 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?
