1. The problem statement, all variables and given/known data Problem statement: In the attached figure, two curved plastic rods, one of charge q and the other of charge q, form a circle of radius R 8.50 cm in an xy plane. The x axis passes through both of the connecting points, and the charge is distributed uniformly on both rods. If q 15.0 pC, what are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the electric field produced at P, the center of the circle? 2. Relevant equations 3. The attempt at a solution Read solution on Chegg.com My question: Why is it that the electric field only have a component in the x-axis?
