Решение задачи по физике раздел 70 пункт 4 электро

4. The potential difference between the plates of a flat capacitor is 900 V. The capacitance of the capacitor is 200 pF. The space between the plates of the capacitor is filled with glass with a dielectric constant ε = 6. What work must be done to remove the glass from the capacitor, after disconnecting it from the voltage source? (Friction neglected).
