Two Parallel Plate Capacitors,C₁ and C₂ Are Connected in Series $\varOmega$

question 39

Multiple Choice

Two parallel plate capacitors,C₁ and C₂ are connected in series to a 60-V battery,a switch S,and a 200-K $\varOmega$ resistor as shown in the figure.Both capacitors are air gap capacitors and have plates with an area of 2.0 cm² and a separation of 0.10 mm.The capacitors are initially uncharged and switch S is open.After switch S is closed,how long will it take for the capacitors to charge to 50% of their maximum value?
