A proton moving at $v_0=3\mathrm{.}10{10}^6\frac{m}{s}$ enters the region between two parallel plates with charge densities of magnitude $=2\mathrm{.}40{10}^{-9}\frac{C}{m^2}($see the figure below$).$

$($a$)$ Calculate the magnitude of the electric field $($in $\frac{N}{C})$ between the plates.

N$/$C

$($b$)$ Calculate the magnitude of the electric force $($in N $)$ acting on the proton.

N

$($c$)$ Find the $y-$location of the proton $($in m $)$ when it reaches the far edge of the plates, a horizontal distance $d=4\mathrm{.}50{10}^{-2}m$ from where it entered. Assume that the proton does not hit either of the plates. $($Assume the $+x$ direction is to the right and the $+y$ direction is up$.)$

Answer part C please.
