Use Gauss's Law to find the electric field due to a) a point charge, b) an infinite line of charge and c) an infinite sheet of charge. The working form of Gauss's Law is E=Q in/Aεo where Qin is the charge inside the Gaussian surface and A is the surface area of the Gaussian surface through which the electric field is parallel to the area vector.
