In the air over a particular region, at an altitude of 500 m above the ground, the electric field is 150 N/C directed downward. At 600 m above the ground, the electric field is 100 N/C downward. What is the average volume charge density in the layer of air between these two elevations?

charge denisty should be in C / m^3

so given field strength at different altitudes

use

E = kQ / r^2 to solve for Q for each altitude

then

charge density = Q / (4/3π r^3)

radius of Earth is 6378100 m

so respecitive heights are 6378600m and 6378700m

then average these or subtract or sumthing

is this process somewhat correct?
