Weight of a body in a water column

  1. Feb 20, 2012 #1
    The weight of a body is less when it is submerged in water, due to the upthrust.
    But the weight of the water column above the body can be far more than the upthrust(weight of the displaced water).
    So is it not that the weight of a body can increase when it is submerged in water?

    The water above you also pushes on all the water around you, which in turn ends up pushing you up from below (since pressure act in all directions). This push up is always greater than the push down.
