Problem 29. Show by direct integration that the electric field at the center of a ring of charge of radius R and of constant linear charge density A is zero. Let the ring be in the z-y plane, centered on the origin of coordinates. You may assume that A is positive. Problem 30 Consider a ring of charge of radine R cantare on the origin in the plane with a linear rharge density is
