Three point charges are located it the positive x-axis of a coordinate system. Positive point charge q1 = 5 nC and negative point charge q2 = -10 nC, are located 3 cm and 5 cm from the origin respectively. Determine the total force of another point charge Q = -1 µC at the origin due to the other two chargers.
