A +7.00 µC particle is located at x = 0.0 cm, and a –9.0 μC particle is located at x = 40.0 cm. Where must a positive test charge be placed along the x–axis so that the net electric force on it is zero? Hint: In a FBD, place the test charge left of x = 0 cm, in between the two source charges, and right of x = 40 cm. Sketch the direction and relative magnitude of the net force at each location and determine where it might be possible for the net force to be zero. Then set the magnitudes of the forces equal to each other.
