A finite line of charge with linear charge density

$=2\mathrm{.}60{10}^{-6}\frac{C}{m}$ and length $L=0\mathrm{.}676m$ is located

along the $x$ axis $($from $x=0$ to $x=L).$ A point charge of

$q=-6\mathrm{.}44{10}^{-7}C$ is located at the point $x_0=1\mathrm{.}00m,$

$y_0=4\mathrm{.}75m.$

Find the electric field magnitude $E$ and direction $($measured

counterclockwise from the $+x$ axis$)$ at the point $P,$ which is

located along the $x-$axis at $x_P=10\mathrm{.}50m.$

The Coulomb force constant is

$k=\frac{1}{4lo{n}_0}=8\mathrm{.}99{10}^9\frac{(N)*m^2}{C^2}.$

$E=|,\frac{N}{C},=$
