The electrostatic force between the metal plates of an isolated parallel plate capacitor \(C\) having a charge \(Q\) and area \(A\) is:
| 1. | independent of the distance between the plates. |
| 2. | linearly proportional to the distance between the plates. |
| 3. | proportional to the square root of the distance between the plates. |
| 4. | inversely proportional to the distance between the plates. |

The distance between the two plates of a parallel plate capacitor is doubled, and the area of each plate is halved. If \(C\) is its initial capacitance, its final capacitance is equal to:
| 1. | \(2C\) | 2. | \(\dfrac{C}{2}\) |
| 3. | \(4C\) | 4. | \(\dfrac{C}{4}\) |

A parallel plate air capacitor is charged to potential difference \(V\). After disconnecting the battery, the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates:
| 1. | decreases. | 2. | increases. |
| 3. | becomes zero. | 4. | does not change. |
