24. A parallel-plate capacitor (plate area is A = 6.0 m² and the two plates are separated by d = 5.0 mm), filled with a dielectric with the dielectric constant K=3.2, is connected to a 120 Volt battery. After the capacitor is fully charged, the battery is then disconnected. Calculate the work required to remove the dielectric. [The permittivity of free space is ε0 = 8.85×10⁻¹² C²/Nm²].
(A) 0 Joule
(B) 4.1×10⁻⁴ Joule
(C) 2.2×10⁻⁴ Joule
(D) 5.4×10⁻⁴ Joule
