1. The problem statement, all variables and given/known data Two parallel charged wires are in vacuum. Width of wires is equal to the distance between them. Calculate electric field in the middle (point A). 2. Relevant equations Superposition 3. The attempt at a solution Using superposition, y components on vector E are cancelled. I get that the electric field at point A is EA=√2 λ/(πε0a) In my books solution, it is EA=λ/(2ε0a) Is my solution correct? Note: I used integration by angle component. Thanks for replies.
