P1. A plane parallel capacitor, whose plates are each of area A and separation d, is charged with a battery of EMF V. How much work is done if a large metallic slab with thickness d/3 is inserted inside the capacitor? The slab is parallel with the plates. The capacitor is connected to the battery while we move the metallic slab, so the potential of the capacitor is fixed. d metal d/3 A
