a. Calculate the magnitude of the electric field due to the plane of charge. b. Suppose the particle passes through a small hole in the plane of charge (i.e., the particle does not collide with the plane, but passes straight through it). Sketch the path of the particle after it passes through the hole. c. How far away from the plane of charge is the particle 2.0 s after it passes through the hole?
