If a positive charge resides at z = a and a negative charge resides at z = -a, then the potential along the z 0 plane is zero everywhere. how much work is required to bring a third charge, 3 in from an infinite distance away to the origin (0,0,0)? answer along the following paths, and provide a) along the x-axis, from x = 00 to x = 0. b) along the y-axis, from y = 00 to y = 0. c) along the path l = xa + xy xz from x = o to x 0. an explanation for your
