Capacitor Charge with Dielectric Insertion
An air-filled parallel-plate capacitor has a capacitance of C₀. It is connected to a battery and acquires a charge of Q₀. While the capacitor remains connected to the battery, a dielectric with a permittivity of 3ε₀ is inserted, filling half the volume between the plates. What is the new charge on the capacitor?
