The Earth producesan approximately uniform electric field at ground level. This electricfield has a magnitude of 110 N>C and points radially inward, towardthe center of the Earth. (a) Find the surface charge density (sign andmagnitude) on the surface of the Earth. (b) Given that the radius ofthe Earth is 6.38 * 106m, find the total electric charge on the Earth.(c) If the Moon had the same amount of electric charge distributeduniformly over its surface, would its electric field at the surface begreater than, less than, or equal to 110 N>C?
