Estimate the buoyant force exerted on your body by the air

  1. May 2, 2009 #1
    Estimate the buoyant force exerted on your body by the air ( use Pair+1.029 kg/m^3). What would be the difference between your weight in the air and your weight in a vacuum?
    How would I proceed with this? What Equation should I use?

    Archimedes' principle states that the buoyant force on an object in a fluid is equal to the weight of the displaced fluid. That should be a good starting place.

    just multilpy volume of body and density of air and accleration due to gravity. your weight will be more in vacuum.
