Problem 4 A point charge -q is located at the origin. The point charge is surrounded by a ring with uniform line charge density and radius a. The charged ring sits in the x-y plane and is centered on the origin. a) Calculate the electric potential along the z-axis using a reference point at o using Coulomb's law for V. (i.e. do not find the electric field first.) b) Use E= -VV to calculate the electric field along the z-axis....
