Now we will instead assume that $q_2$ is negative: $q_1=+9\mathrm{.}1nC$ and $q_2=-1\mathrm{.}5nC.$

What is the $x-$component of the electric field due to charge $q_2$ at point $P?$

$($Remember: the $x-$component of the electric field at point $P$ due to charge $q_1$ is still $+1,309\frac{N}{C}.)$

What is the strength $($or magnitude$)$ of the net electric field at point $P?$
