A balloon has volume of `1000 m^(3)`. It is filled with hydrogen `(rho=0.09 gL^(-1))`. If the density of air is `1.29 gL^(-1)`, it can lift a total weighht of

600 kg

2400 kg

300 kg

1800 kg

Text Solution

Verified by Experts

The correct Answer is:

`1 gc^(-1)=1 kgm ^(-3)`
Upthgrust = total downward force
`therefore" "2000xx129xxg=(2000xx0.09xxg+mg)`
m = 2400 kg
