Considering the pressure 'P' to be proportional to the density of air 'd', the pressure at height 'h' if the pressure on surface of earth is 'P_(0)' and density 'd_0', under isothermal conditions

Answer»

<P>`P_(0) E^( - (P_0)/( d_0) GH)`
`P_(0) e^(- ( d_0)/( P_0) gh)`
`P_(0) e^(( d_0)/(P_0) gh)`
`P_(0) e^( ( P_0)/( d_0)gh)`
