Question

Three charges are located in the x-y plane (see plot below), with Q1 =-5.00 C, Q2 = 7.00 C and Q3 = 3.00 C. Note that the charges are located at grid intersections points. 4 3 2 1 1 2 -3.91 4 -5-4-3-2-1 1 2 3 4 5 x (m) Calculate the total electrostatic potential energy. 6.72×10- J You are correct. Your receipt no. is 162-5130e vious Trie Calculate the work required (by external forces) to transport Q2 from its location on the figure to infinity -4.20*10 (-3) J Submit Answer Incorrect. Tries 5/12 Previous Tries

Explanation / Answer

Work required

= change in potential energy

= PEinfinity - PElocation

= 0 - (-6.72 x 10-2)

= 6.72 x 10-2 J
