Question

The density of atmosphere varies with height H above the ground as per relation , $\rho ={\rho }_0{e}^{-aH}$, where a is a constant. The pressure at a height h is:

• A. $\frac{{\rho }_0}{a}g{e}^{aH}$
• B. $\frac{{\rho }_{0}g{e}^{aH}}{h}$
• C. $\frac{{\rho }_{0}g{e}^{-aH}}{h}$
• D. $\frac{{\rho }_{0}g{e}^{-aH}}{a}$

Answer 1

The correct option is D $\frac{{\rho }_{0}g{e}^{-aH}}{a}$

Correct answer should be D.
