Two thin rods of length L lie along the x-axis, one between x=a/2 and x=a/2 + L and the other between x=−a/2 and x=−a/2 − L. Each rod has positive charge Q distributed uniformly along its length. Calculate the electric field produced by the second rod at points along the positive x-axis. Express your answer in terms of the variables x, a, L, Q and constant k.Find the magnitude of the force that one rod exerts on the other. Express your answer in terms of the variables a, L, Q and constant k.
