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

Explanation

a. E = 0 , electric field will be cancelled due to both.
v. `sigma//epsilon_0` to the right, field of both with be added.
c. E = 0, electric field will be cancelled due to both.
