Textbook Question

Chapter 25, Problem 30PQ

Two very long, thin, charged rods lie in the same plane (Fig. P25.30). One rod is positively charged with charge per unit length +λ, and the other is negatively charged with charge per unit length −λ. The perpendicular distance between the rods is R. Using the coordinate system shown in the figure, sketch the electric field as a function of r from −R to +2R.
