The Earth’s surface, on average, carries a net negative charge (while the clouds and lower atmosphere carry a net positive charge of nearly equal magnitude), giving rise to an electric field at its surface which is about 150 N/C in size.1 Assuming a spherical Earth, determine(a) the total charge on Earth’s surface responsible for this field and the corresponding surface charge density.(b) Given the 150 N/C field at Earth’s surface, how much lower is the field strength right below a cloud at a height of 5 km? [Careful for rounding errors here.]
