Two identical air-filled parallel-plate capacitors C1 and C2are connected in series to a battery that has voltage V. The charge oneach capacitor is Q0. While the two capacitors remain connected to thebattery, a dielectric with dielectric constant K > 1 is inserted betweenthe plates of capacitor C1, completely filling the space between them.In terms of K and Q0, what is the charge on capacitor C1 after the dielectricis inserted? Does the charge on C1 increase, decrease, or staythe same?

Question

Two identical air-filled parallel-plate capacitors C1 and C2
are connected in series to a battery that has voltage V. The charge on
each capacitor is Q0. While the two capacitors remain connected to the
battery, a dielectric with dielectric constant K > 1 is inserted between
the plates of capacitor C1, completely filling the space between them.
In terms of K and Q0, what is the charge on capacitor C1 after the dielectric
is inserted? Does the charge on C1 increase, decrease, or stay
the same?
