A balloon has volume of `2000 m^(3)`. It is filled with hydrogen`(rho=0.009 gL^(-1))`. If the density of air is `1.29 gL^(-1)`, it can lift a total weight of

A

600 kg

B

2400 kg

C

300 kg

D

1800 kg

Text Solution

Verified by Experts

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