An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.37 μc/m2. another infinite sheet of charge with uniform charge density σ2 = -0.19 μc/m2 is located at x = c = 28 cm.. an uncharged infinite conducting slab is placed halfway in between these sheets ( i. e., between x = 12 cm and x = 16 cm). what is ex(p), the x-component of the electric field at point p, located at (x, y) = (6 cm, 0)?
