How to proceed Charge q_(2) will attract charge q_(1) (along the line joining them) and charge q_(3) will repel charge q_(1) . Therefore, two forces will act on q_(1) , one due to q_(2) and another due to q_(3) . Since , the force is a vector quantity both of these force (say F_(1) and F_(2) ) will be added by vector method. Following are two methods of their addition
