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 parallel plate capacitor is connected to a battery as shown in the figure. Consider two situations.

                                          

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.
Choose the correct option(s).
1. (a), (b) only
2. (b), (c) only
3. (a), (c), (d) only
4. (c), (d) only
