A charge $+q$ is located at $3\mathrm{.}000cm,$ a second charge $-2q$ is located at $8\mathrm{.}000cm,$ and a third charge $+q$ is located at $11\mathrm{.}00cm.$ The magnitude of $q$ is $1\mathrm{.}250C.$

Assume that the positive direction is to the right, and use $k=8\mathrm{.}988109N*\frac{m2}{C2}$ for the Coulomb constant.

What is the force $F_x$ on the charge located at $x=8\mathrm{.}000cm?$

$F_x=$
