A parallel$-$plate capacitor is formed from two $8\mathrm{.}0-$cmcm$-$diameter electrodes spaced $2\mathrm{.}6$ mmmm apart. The electric field strength inside the capacitor is $4\mathrm{.}0106$N$/$C$4\mathrm{.}0106$N$/$C$.$

Part A

What is the magnitude of the charge $($in nCnC$)$ on each electrode?
