A total positive charge is distributed uniformly along a thin, straight rod of length L. The rod lies along the x-axis with its left end at the origin as shown in the figure below. (a) Set up correct integrals with the appropriate limits of integration for the x-component and y-component of the electric field at P. Do not evaluate the integrals here. You must indicate/sketch, on the figure, your dx, r, dq and the corresponding de and its components dEx and dEy at P to receive full credit (b) Evaluate your integrals and give the net electric field at P. If you think one of the components is zero, then explain why it is zero. (c) What is the electric field at P for d >> L? Explain. + Q
