Homework Help: Net force of a baloon?

  1. Nov 22, 2009 #1
    So I have the mass, volume, and the density of the gas inside it.....how do i work out the net force?

    Is it to do with working out weight and then viscous drag?

    hi pipjordan - you need to be clearer in defining the question, its a little difficult to guess what you're trying to do

    that said balance all the forces, including:
    - mass
    - bouyancy
    - viscous drag
