QUESTION:

With the switch in position A, the \(11.2 \mu F\) capacitor in Figure 21–42 is fully charged by the \(12.0-V\) battery, and the \(9.50-\mu F\) capacitor is uncharged. The switch is now moved to position B. As a result, charge flows between the capacitors until they have the same voltage across their plates. Find this voltage.
