Assuming that the atmosphere has the same density anywhere as at sea level `(rho =1.3 kgm^(-3))` and g to be constant `(g=10 ms^(-2))`. What should be the approximate height of atmosphere ?
`(rho_(0)=1.01xx10^(5)Nm^(-2))`

A

6 km

B

8 km

C

12 km

D

18 km

Text Solution

Verified by Experts

The correct Answer is:
B
1 atmosphere`=1.01xx10^(5) Nm^(-2) =rho gh`
`therefore " " h=(1.01xx10^(5))/(1.3xx10)=7769 m ~~ 8 km`
