We suppose the existence of a uniform electric field E0= 532 i N/C without specifying which charges are the cause. To this field is added that of a point charge q1 = 4uC located at the origin. What is the resulting electric force acting on a charge q2 = 7uC located at the point ( 2.5 m; 5.7 m)?

F2 = [i + i ] 10 N
