Upthrust problem.

  1. Mar 18, 2013 #1
    I got confused with the Archimedes theory.

    I want to ask if upthrust equals to the weight of the fluid displaced by the object, or is it the weight of the object itself?

    I thought it should be weight of fluid since fluid has it's own density which determines it's mass which in turns affect the weight acting upwards....But i did came across some people who say that it has to be the actual weight of the object in order to achieve equilibrium. :confused:

    If the upthrust always equals the weight, can any body ever NOT be in equilibrium? And what happens in reality?
