A very thin plastic rod of length Lis rubbed with cloth and becomes uniformly charged with a total charge of -Q Consider an arbitrary piece of rod of length de located at a position on the rod. Find an expression for the electric field dE at observation location a distance d to the right of the rod and a distance h above the horizontal axis as indicated. Use a coordinate system in which the origin is located at the left end of the rod and + points right. When entering your solutions, use k for Coulomb's constant.
