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 and direction 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 × 10-19c) ε0 = 8.85 × 10-12 c2/n • m2)

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
