A balloon weighting 50 kg is filled with 685.2 kg of Helium at 1 atm. pressure and at 25°C.What will be its pay load, if it displaced 5108 kg of air?(A) 437.28 kg (B) 43.728 kg(C) 4843.2 kg (D) 4372.8 kg

Answer»

Payload can be explained as the difference between the mass of the air displaced and that of the mass of the balloon. It is important to note that the mass of the balloon is the sum total of mass of balloon skin itself and the mass of the Helium filled in it.

Hence, Payload = 5108 Kg - (50 Kg + 685.2 Kg) = 4372.8 Kg.
