Two thin parallel conducting plates are placed $2\mathrm{.}1$m apart. Each plate is $2\mathrm{.}1$ cm on a side; one plate carries a net charge of $8\mathrm{.}6$C$,$ and the other plate carries a net charge of $8\mathrm{.}6$C$.$ What is the charge density $($in C$/$m$2)$ on the inside surface of each plate? $($Enter the magnitude.$)$

C$/$m$2$

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

N$/$C
