There are two point charges q$1=(9\mathrm{.}000$x$10^0)$C and q$2=(-9\mathrm{.}0000$x$10^0)$C$.$ q$1$ is located at origin $(0,0).$ q$2$ is located at $((5\mathrm{.}00$x$10^0)$ m$,(4\mathrm{.}0000$x$10^0)$ m$).$ Please calculated the x$-$component of the electrostatic force on q$1.$ Give your answer in the unit of N with $3$ sf$.$

Note: Use the sign to represent the direction, for example $-2\mathrm{.}11$x$10^-4$ means the force is on the negative x direction.
