A point charge q1 = 3.90 nC is placed at the origin, and a second point charge q2 = -3.00 nC is placed on the x-axis at x=+ 20.5 cm . A third point charge q3 = 1.95 nC is to be placed on the x-axis between q1 and q2. (Take as zero the potential energy of the three charges when they are infinitely far apart.) Part APart complete What is the potential energy of the system of the three charges if q3 is placed at x=+ 11.0 cm ? UU = −4.46×10−7 J SubmitPrevious Answers Correct Part B
