Two identical air-filled parallel-plate capacitors C₁ and C2

Last updated: 7/10/2022

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 Qo. 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. What is the charge on capacitor C₁ after the dielectric is inserted? Express your answer in terms of K and Qo.
