Three point charges are arranged along the x-axis.
Charge q1 = +3.75 µC is at the origin, and
charge q2 = -5.25 µC is at x = 0.300
m. Charge q3 = -9.00 µC. Where is
q3 located if the net force on
q1 is 6.00 N in the −x-direction?

Three charges lie along the x-axis. One positive charge, q1 = 25
uC is at x = 0.25 m. Another charge, q2 = -5.0 uC, is located at
the origin. A third charge, q3 = -35 uC, is placed so that q2 is in
electrostatic equilibrium with q1 and q3. How large must the
electrostatic force between q2 and q3 be to balance the force
between q1 and q2?
