Chapter 22
Coulombs Law-
Sum the forces style problems-
Chapter 23
Electric Field-
Electric Field due to a point charge -
Electric Field due to a dipole -
p has a magnitude of qd and points in the
direction of the negative charge to the positive
charge. z is the distance from the center of the
dipole to the point where the electric field is
being measured
