ANSWER
The net charge on both capacitors is the same
Step-by-step explanation
The net charge of a capacitor is the sum of the individual charges of each plate of the capacitor.
On a charged capacitor, both plates have the same amount of charge - but opposite. Therefore, the net charge is zero.
On an uncharged capacitor each plate has zero charge, so the net charge is also zero.
Hence, the net charge is always the same: zero.
