APFIVE Capacitor Charge with Dielectric Insertion
A parallel-plate capacitor with air between its plates has capacitance C₀. When connected to a battery, it stores charge Q₀. While still connected to the battery, a dielectric with permittivity 3ε₀ is inserted to fill half the volume between the plates. What is the new charge on the capacitor?
