As shown in the figure, point charge $q_{1}$ is $4.671 \mu \mathrm{C}$ and is located at $x_{1}=-3.573 \mathrm{~m},$ and point charge $q_{2}$ is $6.845 \mu \mathrm{C}$ and is located at $x_{2} .$ The $x$ -coordinate of the point where the net force on a point charge of $-1.000 \mu \mathrm{C}$ is zero is $4.625 \mathrm{~m}$. What is the value of $x_{2} ?$
