Two infinite, nonconducting sheets of charge are parallel to each other as shown in Figure P24.56. The sheet on the left has a uniform surface charge density , and the one on the right is has a uniform charge density of . Calculate the electric field at points-
(a) to the left?
(b) to the right?
(c) in between?
(d) Find the electric fields in all three regions if both sheets have positive uniform surface charge densities of ?
