Two objects, both positively charged are on the xy plane. One object can be thought of as a point charge +q located at (0, -b) and the other object is a section of a ring of radius b centered at the origin with total charge +q as shown in the figure. Given that the ring section is uniformly charged, find the net electric field at the origin due to both objects. (0,b) (0,-b) extended Chart (6.0)
