Consider three capacitors C1, C2, and C3 and a battery. If only C1 is connected to the battery, the charge on C1 is 31.6 µC. Now C1 is disconnected, discharged, and connected in series with C2. When the series combination of C2 and C1 is connected across the battery, the charge on C1 is 22.9 µC. The circuit is disconnected, and both capacitors are discharged. Next, C3, C1, and the battery are connected in series, resulting in a charge on C1 of 26.0 µC. If, after being disconnected and discharged, C1, C2, and C3 are connected in series with one another and with the battery, what is the charge on C1?
