Three 1.0 {rm nC} charges are placed as shown in the figure. Each of these charges creates an electric field vec E at a point 3.0 {rm cm} in front of the middle charge. What are the three fields vec E_1, vec E_2, and vec E_3 created by the three charges? Write your answer for each as a vector in component form.
