On a clear, sunny day, there is a vertical electrical field of about 63 N/C pointing down over flat ground or water. This field is due to positive charge in the upper atmosphere of the earth (the ionisphere) inducing a negative charge on the earth’s surface. Thus the field lines stop at the surface. What is the magnitude of the surface charge density on the ground for these conditions? The permittivity of free space is 8.85419 × 10−12 C 2 /N · m2 . Answer in units of C/m2
