Find the height of atmosphere.

The density of asir ner earth's surface is 1.3kgm^-3 and the atmospheric pressure is 1.0xx10^5Nm^-2 . If the atmosphere had uniform density, same as that observed at the surface of the earth what would be the height of the atmosphere to exert the same pressure?

What would be the height of the atmosphere if the air density (a) were uniform and (b) decreased linearly to zero with height? Assume that at sea level the air pressure is 1.0 atm and the air density is 1.3 kg/ m^(3)

Oxygen gas is in negligible quantity at the height of atmosphere:

Diameter of a planet is 10d_(@) , its mean density is (rho_(@))/(4) and mass of its atmosphere is 10m_(@) where d^(@) , rho^(@) and m^(@) are diameter, mean density and mass of atmosphere respectively for the earth. Assume that mean density of atmosphere is same on the planet and the earth and height of atmosphere on both the planets is very small compared to their radius. Find the ratio of atmospheric pressure on the surface of the planet to that on the earth. If a mercury barometer reads 76 cm on the surface of the earth, find its reading on the surface of the planet.
