The space between the plates of a flat capacitor is filled with a dielectric (porcelain, ɛ = 5), the volume V of which is 100 cm3. Surface charge density o = 8.85 nC / m2. Calculate the work A to be done to remove the dielectric plate from the capacitor. Friction is neglected. Consider two cases: a) the capacitor is disconnected from the voltage source; b) the capacitor is connected to a power source with a voltage of U = 20 V.
