Q. No.Given below are two statements:
| Assertion (A): |
Two straight current-carrying conductors A and B are lying in a vertical plane as shown. The separation between them is h and mass per unit length is . Keeping A fixed, when B is raised by a small height dh, the net work done by external force per unit length will be gdh. |
| Reason (R): | The work done by magnetic field during this process is non-zero. |
| 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. |

NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyGiven below are two statements:
| Assertion (A): | Two parallel wires carrying current in the same direction attract each other, whereas two proton beams moving parallel to each other repel each other. |
| Reason (R): | Wire-carrying current is electrically neutral, therefore it is experiencing only magnetic attraction while the electric force of repulsion between protons is more than magnetic attraction. |
