An inflated balloon of volume 1000 cm3 is filled with helium. (a) What is the weight of the balloon? (b) What is the magnitude of the buoyant force acting on it? (c) What is the magnitude and direction of the net force acting on it? The density of air is 1.29 kg/m3 , the density of helium is 0.179 kg/m3 , and the mass of the uninflated balloon is 1.0 g. (There is currently a severe shortage of helium, so helium balloons are becoming less common.)
