Two charges are located in the $(x,y)$ plane as shown. The positive $x$ direction is to the right and the positive $y$ direction is upwards. The fields produced by these charges are observed at a point $p$ with eoordinates $(0,0).$

Find the $x-$component of the electric field at $p.$ The value of the Coulomb constant is $8\mathrm{.}98755{10}^{9}N*\frac{m^2}{C^2}.$

Answer in units of $\frac{N}{C}.$
