Consider a helium balloon with volume 2.15 L. a. Calculate the buoyant force on the balloon, in newtons. Use 1.29 kg/m3 for the density of air. b. Given the mass of the rubber in the balloon is 1.65 g, what will be the net force, in newtons, in the vertical direction (taking up as positive) on the balloon if it is released? Neglect the volume of the rubber, and use 0.18×10-3 g/cm3 for the density of helium.
