Ans: Given that , d= 6m , density = 0.561 kg/m³ and density of air = 1.225 kg/m³
Volume = (4/3)*π*r³
= (4/3)*3.14*(3)³ = 113.04 m³
Weight of balloon = volume x density
= 113.04*0.561 = 63.42 kg
Mass of displaced air = 113.04*1.225 = 138.474 kg
Weight of displaced air = 138.272 * 9.81 = 1358.43 N
Maximum load the balloon can carry = 1358.43/9.81 = 138.474kg + self weight
= 138.474+63.42 = 201.894 kg
