A flat, wide cloud floats horizontally a few kilometers above the surface of Earth. Its lower surface carries a uniform surface charge density of -2.6×10-4 C/m2 , while there is no excess charge elsewhere in the cloud. What is the magnitude of the electric field, in newtons per coulomb, a few meters below the cloud, under the cloud’s approximate center, due to the charge distribution?
