Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb = ? airgVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 70 kg each, Determine the maximum amount of load, in kg . Assume the density of air is ? =1.16kg/m3, and neglect the weight of the ropes and the cage
