The peak concentration ozone above surface of Earth is at:

The peak concentration of ozone above the surface of earth is present at a height of .

The height of geostationary orbit above the surface of the earth is h. Radius of the earth is R. The earth shrinks to half its present radius (mass remaining unchanged). Now hat will be height of a geostationary satellite above the surface of the earth?

The ratio of the height above the surface of earth to the depth below, the surface of earth, for gravitational accelerations to be the same (assuming small heights) is

Given, acceleration due to gravity on surface of earth is g. if g' is acceleration due to gravity at a height h above the surface of earth, then

What will be the variation of g below and above the surface of earth?

Derive an expression for Gravitational potential above the surface of the earth.
