The electric field just above the surface of Earth has been measured to typically be 163 N/C pointing downward.
What is the total charge on Earth's surface implied by this measurement?
∫EdA = Qinside/ɛo
The Attempt at a Solution
I solved this two ways and got the same answer, which is apparently wrong. using Gauss's Law: EA = Q/ɛo => Q=EAɛo = (-163)(4*pi*r^2)ɛo = -735.56 kC
