A weather balloon filled with helium has a radius of 1m and a mass of 1 kg (linked to ropes and the latex balloon). What is the maximum load of the scientific package this balloon can raise when it floats at an altitude where the helium density is 0.16 kg/m3 and the air density is 1.2kg/m3? (assume that only the balloon displaces air).
