a baloon is filled with a lighter gas which occupies a volume of 1500 cubic meters. its mass is 1650 kg (including that of material and gas). This ballon is tied to a thread and floating in air of density 1.3 kg / m3. calculate the pull on the thread tied to rope

Expert Answer:

Volume of baloon: V= 1500 cubic meter
densiy of air: d = 1.3 kg/cu m
mass of baloon: m = 1650 kg
Buoyant force on baloon = mass of air displaced = F = V x d x g = 1500x1.3x10=19500 N
thus force on baloon due to the tension in rope: 19500-1650(10) = 3000N
