Two small charged objects are located on the y-axis. One is at y = 1.00 m, the other is at y = −1.00 m, and they both have a charge of q = +1.60 µC. (a) Determine the electric potential (in kV) on the x-axis at x = 0.600 m.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
