Consider a spherical conductor of radius r, centred at the point O. A point charge q (q > 0) is placed outside the sphere, at a distance 'd' from its center (O) (d > r) and the sphere is earthed.
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
In the light of the above statements choose the correct answer from the options given below:
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | The electric flux due to the external charge q and the induced charges on the sphere through the spherical surface S shown dotted in the diagram, is (-q/\(\varepsilon_0\)). |
| Reason (R): | Negative charges are induced on the surface of the conducting sphere due to the positive charge q in the vicinity, and the potential of the conducting sphere is zero. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | (A) is false but (R) is true. |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
In the light of the above statements choose the correct answer from the options given below:
| Assertion (A): | Absolute potential at any point is meaningful only when some reference level for the potential is defined. |
| Reason (R): | The capacitance of any parallel plate capacitor depends on the charge on the capacitor and the voltage applied across the plates. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |

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. |
Choose the correct option(s).
1. In A: Q remains same but C changes. In B: V remains same but C changes.
2. In A: V remains same and hence Q changes.
3. In B: Q remains same and hence V changes.
4. Both (2) and (3).
