ICSE Class 9 Answered

A balloon of volume 800 centimetre cube is filled with hydrogen gas of density 9 x 10 raise to power minus 5 gram per centimetre cube. If the empty balloon weighs 0. 3 gf and density of air is 1. 3 x 10 raise to power minus 3 gram per centimetre cube, calculate the lifting power of balloon

answered-by-expert Expert Answer
empty weight of balloon + weight of gas = 0.3×980+800×9×10-5×980  = 365 dyne
 
upward thrust = 800×1.3×10-3 × 980 = 1019 dyne
 
lifting force = 1019 - 365 = 654 dyne
