A point charge +6.5 uC is placed at the origin, and a second charge –3.6 uC is placed in the x-y plane at (0.40 m, 0.50 m). Where should a third charge be placed in the plane so that the net force acting on it is zero?

Three point charges are placed on the x-axis as follows: 20 uC at x = 0; 30uC at x = 0.50 m; and -12 uC at x = 1.2 m Find the net force on the 20 uC point charge. Assume the direction of the x-axis as positive.
