Question:

Two infinite, non-conducting sheets of charge are parallel to each other, as shown in Figure P24.62. The sheet on the left has a uniform surface charge density a, and the one on the right has a uniform charge density -4. Calculate the electric field at points
(a) To the left of,
(b) In between, and
(c) To the right of the two sheets.
