In the air over a particular region at an altitude of 219 m above the ground, the electric field is 141 n/c directed downward. at 319 m above the ground, the electric field is 103 n/c downward. what is the average volume charge density in the layer of air between these two elevations? (include appropriate sign in the answer).
