Two identical capacitors Ca and Cb of capacitance 5.10 μF areconnected in series across a total potential of 690 V. A dielectricslab of dielectric constant 4.35 can fill Ca and is slowly insertedinto that capacitor. (Note, account for any energy change by acorresponding energy change in some other part of the system.)
