Two point charges are placed on the x-axis as follows:
Charge q1 = +3.95 nC is located at x = 0.190 m and charge q2 = -5.50 nC is at x = +0.400 mm. 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 is the direction of the net force exerted by these two charges on a negative point charge q3 = -0.610 nC placed at the origin?
