You have a thin wall of plastic that's quite large (4.0 m x 5.0 m), and decide to rub fur all over the wall until a total charge of ~300. nC is uniformly spread over the wall on one side only. You wish to calculate the strength of the electric field at a point P which is 2.0 cm away from the wall. From the perspective of point P, the wall edges are so far away that the wall appears infinitely large. b) Using Gauss' Law, calculate the electric field vector E at point P. Begin by drawing a Gaussian surface on which you 'll do you're analysis, and be sure to label the direction of the electric and area vector on each section of your Gaussian surface. Be clear in your steps when using Gauss' Law to solve this problem. Symbols should be used in your solution before plugging in numbers. Express your final answer for E in unit-vector notation. c) Now you decide to release a proton from rest at point P. What force will the proton experience? Express your answer in unit-vector notation. * d) At what speed will the proton strike the wall? Note: 1 nC = 1 x 10'9 C.
