Two identical capacitors in series with plate area A and between plates d are connected to a constant voltage DeltaV = 10V as shown in Figure 1. After the capacitors are fully charged, the switch is opened and the dielectric constant k = 4.0, thickness d and surface area A/2 are placed. Accordingly, what is the potential difference (Vb-Va) between the terminals of the capacitors in volts?
