A potential difference V = 4.200×102V is
applied to two capacitors connected in series. One capacitor, C1,
is 4.60 ?F and the other, C2, is 7.50 ?F.
The charged capacitors are disconnected carefully from each
other and from the battery. They are then reconnected, positive
plate to positive plate and negative plate to negative plate, with
no external voltage being applied. What is the charge on the
positive plate of C1?
