What is $${\left(F_{\text{net }}\right)}_x$$, the $$x$$-component of the net force exerted by these two charges on a third charge $$q_3=55.0\mathrm{nC}$$ placed between $$q_1$$ and $$q_2$$ at $$x_3=?1.085\mathrm{m}$$ ? Your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in newtons to three significant figures. Coulomb's law for the magnitude of the force $$F$$ between two particles with charges $$Q$$ and $$Q^{?}$$ separated by a distance $$d$$ is $$?F?=K\frac{?Q{Q}^{?}?}{d^2}$$ where $$K=\frac{1}{4?{?}_0}$$, and $${?}_0=8.854\times 10^{?12}{\mathrm{C}}^2/\left(\mathrm{N}?{\mathrm{m}}^2\right)$$ is the permittivity of free space. Consider two point charges located on the $$x$$ axis: one charge, $$q_1=?20.0\mathrm{nC}$$, is located at $$x_1=?1.745\mathrm{m}$$; the second charge, $$q_2=30.5\mathrm{nC}$$, is at the origin $$(x=0)$$.
