What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q3 = 49.0 nC placed between q1 and q2 at x3 = -1.145 m ? Your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in newtons to three significant figures.
