A uniform electric field exists between two parallel plates separated by $3\mathrm{.}00$ cm$.$ The intensity of the field is $80\mathrm{.}0$ kN$/$C$.$ What is the potential difference $($in kV$)$ between the

plates?

A uniform electric field of $6\mathrm{.}30$ V$/$m exists between the plates of a parallel plate capacitor. How much work $($in $\backslash$mu J$)$ is required to move a $+16\mathrm{.}0\backslash$mu C point charge from the negative plate to the positive plate if the plate separation is $3\mathrm{.}00$ cm$?$lates?
