A very thin rod of length 0.4 m, has a total charge of +10 uC uniformly lies along the x-axis. (a) Draw a diagram of for part (b), labeling your known and unknown variables, and include a coordinate system. (b) Set up an integral (or integrals) to determine the electric field (a vector) at a point on the x-axis, 0.1 m away from one end of the rod. (c) find out the net electric field at that point. describe you reasoning and justify your work using the fundamental physics principles and definitions.
