Two parallel, uniformly charged, infinitely long wires carry opposite charges with a linear charge density ? = 5 £gC/m and are 8 cm apart. What is the magnitude and direction of the electric field at a point midway between them and 49 cm above the plane containing the two wires? (The wires are directed into the screen. Take up to be the +y direction and to the right be the +x direction. Assume that xz-plane contains these wires. The positively charged wire is on the left, and negatively charged wire is on the right.)
