A slab of copper of thickness b = 1.64 mm is placed into a parallel-plate capacitor of plate area A = 3.30 cm² and plate separation d = 7.72 mm, the slab is exactly halfway between the plates. Throughout this process the plates of the capacitor are connected to a voltage source that keeps the voltage at a constant V = 575 V. Part 1) What is the capacitance on the slab after the copper is inserted? Cafter = nF Part 2) How much work is done on the slab to move it into place? W = Part 3) What is the strength of the electric field between the positive plate and the slab? N/m
