Question

Two point charges are placed on the x axis as follows: Charge q1=+3.90 nC is located at x=0.220 m and charge q2=-5.70 nC is at x=+0.400 m.What is the magnitude of the net force exerted by these two charges on a third point charge q3=-0.610 nC placed at the origin? What direction of the net force exerted by these two charges on a negative point charge q3=-0.610 nC placed at the origin?
