1. The problem statement, all variables and given/known data Find the magnitude of the electric field these wires produce at point P, which is 60.0cm from each wire 2. Relevant equations E = kQ/r^2, [tex]\lambda[/tex]=Q/L 3. The attempt at a solution I am not exactly sure how to set up the integral, I have the formula of a general case (with no numbers, just letters). But I am confused how to do it with actual numbers, I don't just want to plug numbers into the formula. I want to know how to derive it. Thanks.
