A point charge q1 = 4.00 nC is placed at the origin, and a second point charge q2 = -3.10 nC is placed on the x-axis at x=+ 20.0 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.)

1:What is the potential energy of the system of the three charges if q3 is placed at x=+ 11.0 cm ?

2:Where should q3 be placed between q1 and q2 to make the potential energy of the system equal to zero?
