Two charges are located on the positive x-axis of a coordinate system. Charge q1 = 2.00 × 10−9C, and it is 0.020 m from the origin. Charge q 2 = –3.00 × 10 −9 C, and it is 0.040 m from the origin. What is the electric force exerted by these two charges on a third charge, q 3 = 5.00 × 10−9, located at the origin? (kC = 8.99 × 109 N•m2/C2)
