Problem 3. (a) At what distance from the center of a uniformly charged ring, along its axis of symmetry, is the electric field strength greatest? (b) Plot the electric field strength as a function of distance from the center of a uniformly charged ring along its axis of symmetry. For the plot set kq = 1 and R = 1. Use the plot to check your result from (a). (c) On the same graph also plot the electric field strength as a function of distance from the center of a uniformly charged disk along its axis of symmetry, setting set kq = 1 and R = 1. Finally, add a plot the field of a point charge with kq = 1. Comment on the behavior of all graphs at large distance. [For nice plots, try www.desmos.com/calculator]

The electric field in a point on the central axis of a uniformly charged very thin ring is given by the expression: E = (k*lambda*2pi*R)/((x^2 +R^2)^(3/2)) i cap where R is the radius of the ring, lambda is the linear charge density, and x is the distance of the point on the central axis to the center of the ring.
