It has been experimentally observed that the electric field in a large region of the earth.s atmosphere is directed vertically down. At an altitude of 300m, the electric field is 60Vm^(-1) . At an altitude of 200m, the field is 100Vm^(-1) . Calculate the net amount of charge contained in the cube of 100m edge located between 200m and 300m altitude.
