Two thin 80.0-cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the +x-axis while the other extends along the +y-axis. the rod along the +x-axis carries a charge of −15.0 µc distributed uniformly along its length, and the other rod carries +15.0 µc uniformly over its length. find the magnitude of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e=1.60×10−19 c, ϵ0=8.85×10−12 c2/n · m2)
