1. The problem statement, all variables and given/known data Consider the three charges in the figure below with Q1 = 2.8 µC, Q2 = 4.4 µC, and Q3 = -3.7 µC. A fourth charge q = -4.8 µC is brought from very far away and placed at the origin. http://www.webassign.net/giocp1/18-p-009.gif How much work is required in this process? How much work is required to move q from the origin to a distance that is very far away? 2. Relevant equations PE = -W = -F Δx = -qE Δx 3. The attempt at a solution am i suppose to calculate the PE of each Q?
