Question

Three point charges are located on the positive x-axis of a coordinate system. Charge q1 = 2.0 nC is 2.0 cm from the origin, charge q2 = -4.0 nC is 4.0 cm from the origin and charge q3 = 4.5 nC located at the origin. What is the net force ((a)magnitude and (b) direction) on charge q1 = 2.0 nC exerted by the other two charges?
