Point charges of $27\mathrm{.}0C$ and $35\mathrm{.}0C$ are placed $0\mathrm{.}400m$ apart.

$($a$)$ At what point $($in $m)$ along the line between them is the electric field zero?

$]$ m away from the $27\mathrm{.}0C$ charge

$($b$)$ What $($in N$/$C$)$ is the electric field halfway between them? $($Enter the magnitude.$)$

N$/$C

What is the direction of the electric field?

along the line between the two charges toward the $35\mathrm{.}0C$ charge along the line between the two charges toward the $27\mathrm{.}0C$ charge There is no direction because the magnitude of the electric field is zero.
