A capacitor of \(4~\mu\text{F}\) is connected as shown in the circuit. The internal resistance of the battery is \(0.5Q\). The amount of charge on the capacitor plates will be:
1. \(0\)
2. \(4~\mu\text{C}\)
3. \(16~\mu\text{C}\)
4. \(8~\mu\text{C}\)

| A: | Key \(K\) is kept closed and plates of capacitors are moved apart using insulating handle. |
| B: | Key \(K\) is opened and plates of capacitors are moved apart using the insulating handle. |
Then:
| (a) | In A: \(Q\) remains same but \(C\) changes. |
| (b) | In B: \(V\) remains same but \(C\) changes. |
| (c) | In A: \(V\) remains same and hence \(Q\) changes. |
| (d) | In B: \(Q\) remains same and hence \(V\) changes. |
