What is the charge (in nC ) on positive electrode? What is the charge (in nC) on negative electrode?

A parallel-plate capacitor is shaped from two 1.0 cm x 1.0 cm electrodes spaced 2.4mm aside. The electrical discipline energy contained in the capacitor is 1.0*10^6 N/C .

Q = CV = (εₒA/d)(Ed) = εₒAE = (8.85×10^-12)(0.01)²(10^6)

= 8.85 x 10^-10 C

So we’ve

+0.885 nC on the optimistic electrode and
-0.885 nC on the unfavorable electrode.
