Two plates witn a large surface area A are separated by a distance d where A d2. The plate on the lett has a charge +Q placed on it while the plate on the right has a charge —Q. When writing expressions in this problem use co, not Coulomb's constant part 1) Write an expression to describe the magnitude ot the electric field nalfivay between the plates. part 2) Write an expression tor the potential beüeen the plates. part 3) use this expression to write an expression tor the capacitance ottnese plates.

Machine generated alternative text: Feedback tor Part 1) Q -Q Figure 1 The plates are charged to -HQ and —Q A rectangular prism Guassian surface (dashed line) bisects is set up to bisect the charged plate. The area bisected is a. Taking a Gaussian surface, a prism, such as the one snoun aQ AEO 2AE0 • This electric field (from the -HQ plate) is pointing to the right. The plate on the left, —Q, contributes similarly to this electric field, the electric field also points to the right so: Etotal Marks for this submissiom 0.00/0.33. This submission attracted a penalty of 0.11 Feedback tor Part 2) The potential is calculated using In this case 50th dE and ds are to the right so: Marks for this submissiom 0.00/0.33.

Machine generated alternative text: Feedback tor Part 3) Capacitance is described by: IAVI • In this case Q Marks for this submissiom 0.00/0.33. This submission attracted a penalty of 0.11 A correct answer is , which can be typed in as follows: Q/ epsilon_e) A correct answer — , which can be typed in as follows: A-eo A correct answer , which can be typed in as follows: AEO
