Two point charges are fixed on the Xaxis , q_(1)=12.0mC is located at the origin and q_(2)=-3.0mC is located at point A, with x_(2)=8.0cm . Where should a third charge q_(3) , be placed on the X-axis so that the total, electrostatic force acting on it is zero?

A point charge q_1 = + 2muC is placed at the origin of coordinates. A second charge, q_2 = - 3muC , is placed on the x-axis at x = 100cm . At what point (or points) on the x-axis will the absolute potential be zero?
