Coulomb's law for the magnitude of the force F between two particles with charges Q and Q′ separated by a distance d is |F|=K|QQ′|d2, where K=14π?0, and ?0=8.854×10-12C2/(N⋅m2) is the permittivity of free space.

Consider two point charges located on the x axis: one charge, q1 = -20.0 nC , is located at x1 = -1.720 m ; the second charge, q2 = 39.0 nC , is at the origin (x = 0).

What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q3 = 49.5 nC placed between q1 and q2 at x3 = -1.050 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.
