Problem 1 (30 points) Two uniformly charged rods with charge Q and length L lie along the z-axis as shown in the figure (rods have been fixed in their positions, so they cannot move). (a)(15pts.) Find the electric field created by the left rod at point I where = > L. (b)(15pts.) Find the electric force on the right rod that is applied by the left rod.

Two curved plastic rods, one of charge +q and the other of charge -q, form a circle of radius R in the plane. The horizontal and vertical axes are shown, and the join between the two rods is on the vertical axis. 5. a. Draw a representative sample of electric field lines (with directions) inside and outside the circle. It should look reasonably accurate. Total charge on left half: +q Total charge on right half: q b. If charge is...
