Correct Answer is: (b) 2C Method 1 Before the metal sheet is inserted, C = ɛ 0 A/d. After the sheet is inserted, the system is equivalent to two capacitors in series, each of capacitance C'' ɛ 0 A(d/4) = 4C. The equivalent capacity is now 2C. Method 2 If a dielectric slab of dielectric constant K and thickness t is inserted in the air gap of a …
Step 1/6 1. Initially, the capacitor has a capacitance of Co. Step 2/6 2. When the metal slab is inserted halfway between the plates, it effectively divides the capacitor into two parts: one part with the metal slab and the other part without the metal slab. Step 3/6 3.
