A man is standing beneath two rain clouds, equidistant from each is shown in the figure.Cloud A has an excess of $7\mathrm{.}5$ x$10^4$ negative charges while cloud B $7\mathrm{.}5$x$10^4$ positive charges $($where a charge has magnitude e$).$

$($a$)$ What is the magnitude of the net electric field where the man is standing?

N$/$C

$($b$)$ What is the direction of the net electric field where the man is standing? $($Assume the $+x-$axis is to the right.$)$

counterclockwise from the $+x-$axis
