Law of gravitation
Archimedes principle
Principle of buoyancy
All of the above
Lifting of Balloon:
Hence, the correct answer is option (D).
A balloon of volume 800 cm3 is filled with hydrogen gas ofdensity 9 x 10-5 g/ cm3 .If the empty balloon weighs 0.3 gf anddensity of air is 1.3 x 10-3 g/ cm3 . Calculate the lifting power of the balloon
