Capacitor question

2023 · 10 Apr · Shift 2 · Q56

JEE MainPhysicsCapacitorMCQ+4 / −1
The distance between two plates of a capacitor is d\mathrm{d}d and its capacitance is C1\mathrm{C}_{1}C1​, when air is the medium between the plates. If a metal sheet of thickness 2d3\frac{2 d}{3}32d​ and of the same area as plate is introduced between the plates, the capacitance of the capacitor becomes C2\mathrm{C}_{2}C2​. The ratio C2C1\frac{\mathrm{C}_{2}}{\mathrm{C}_{1}}C1​C2​​ is
