By the way I used chi (χ) as a dummy variable when integrating since I wanted to obtain E as a function of position along the x-axis. Thus, E_1(x= b) = \frac{k Q_1}{b^2-a^2} Edit: I think I might've solve it now. Instead of cancelling 2a out when I calculated E1(x), I just left it. So...

Homework Statement Identical thin rods of length 2a carry equal charges, +Q, uniformly distributed along their lengths. The rods lie along the x-axis with their centers separated by a distance b > 2a. Find the force, F, exerted by the left rod on the right one. Left rod's center @ (0,0) → rod...
