Textbook Question
Chapter 23, Problem 15P
(II) The Earth produces an inwardly directed electric field of magnitude 150 V/m near its surface. (a) What is the potential of the Earth’s surface relative to V = 0 at r = ∞? (b) If the potential of the Earth is chosen to be zero, what is the potential at infinity? (Ignore the fact that positive charge in the ionosphere approximately cancels the Earth’s net charge: how would this affect your answer?)
