1. The problem statement, all variables and given/known data Compute the electric potential energy for the charge configuration shown below. http://webct6.nic.bc.ca/webct/RelativeResourceManager/Template/CourseMaterials/CourseContent_2007FA/Assignments/PHY060W_Assignment_07_files/image025.jpg [Broken] 2. Relevant equations TPE=PE11+PE12+(PE13+PE23) 3. The attempt at a solution TPE=PE11+PE12+(PE13+PE23) | TPE= 0J+[(q1KQ2)/r2] + [(q1KQ3)/r1 + (q2KQ3)/r3] | q1=-3.0 microcoloumb q2=2.0microcoloumb q3=5.0microcoloumb | where q1 is charge 1, q2 and Q2 are charge 2, Q3 is charge 3, r1 is the distance between q1 and Q3, r2 is the distance between charge 1 and 2, r3 is the distance between q2 and Q3. I have chosen charge one to base my calculations off. I had problems before with this question and I was instructed to find charge one due to charge one + PE on charge one due to charge 2 + (PE on charge 1 due to charge 3 + PE on charge 2 due to charge 3) I am not sure why I need to calculate the potential energy on charge 2 due to charge 3. So I need to know if my equation is correct and also why I need to calculate the potential energy of charge 2 due to charge 3 when I am using charge one to base my calculations off of?
