Three infinitely long lines charge are located at x-axis, the line: x = 2, z = 2 (parallel to y-axis) and the line: x = y = z, respectively. They have the same uniform line charge density: 0 = 40 Find the electric field intensity at the point A (2,2,0). I'm really stuck on this problem. I've read the material involving just a single line of a charge but I can find no info involving how to deal with this example in particular. I would love some help on this topic.
