Constant Electric Field in a Vacuum

Problem 3.22

Each of the two long parallel threads carries a uniform charge \(\lambda\) per unit length. The threads are separated by a distance \(l\). Find the maximum magnitude of the electric field strength in the symmetry plane of this system located between the threads.
