Determine what the maximum cargo weight value is that a spherical air balloon filled with hydrogen, which has a density of 0.08375kg/m³, can lift up at 0°C and 1 atm pressure. The balloon has a radius of 8.15 m, and the combined mass of the balloon's structure and skin is 880 kg. Assume that the buoyant force on the cargo itself is negligible.

• A. 1.9 × 10³ N
• B. 2.3 × 10³ N
• C. 3.1 × 10³ N
• D. 4.3 × 10³ N
