An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.25 μC/m2. Another infinite sheet of charge with uniform charge density σ2 = -0.42 μC/m2 is located at x = c = 36 cm.. An uncharged infinite conducting slab is placed halfway in between these sheets ( i. e., between x = 16 cm and x = 20 cm). 1)What is Ex(P), the x-component of the electric field at point P, located at (x, y) = (8 cm, 0)?
