(adsbygoogle = window.adsbygoogle || []).push({}); 1. If the Earth had a net surface charge density of 1.0 electron per square meter a) what would be the total charge on the earth's surface? b) what would be the electric potential and c) what would be the electric field, just outside the earth's surface?

Attempt: I tried using charge of electron (-1.6 x 10^-19C/m^2) and rearranging equations of electrostatics but cannot come up with the answer.

The solutions should be -82microC, -0.12V and 18nV/m
