Electric field outside a capacitor
$begingroup$ The fields outside are not zero, but can be approximated as small for two reasons: (1) mechanical forces hold the two "charge sheets" (i.e., capacitor plates here) apart and maintain separation, and (2) there is an external source of work done on the capacitor by some power supply (e.g., a battery or AC motor). Remove (1) and the two "sheets" will begin to oscillate …

There is a force (F) between the plates.

$begingroup$ @BobD I think it would be that way if the capacitors are of equal value, since that would mean it requires the same amount of charge accumulated to produce a volt on the plates. If C1 is a larger capacitance than C2, it would mean that C1 requires more charge to create a volt, so C2 charges/discharges faster than C1 would, meaning that C2 …
