A : If speed of a particle is never zero than it may have zero averag speed.
R : The average speed of a moving object in a closed path is zero.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statement, then mark (4).

Answer

To analyze the given statements, we need to break down the assertion (A) and the reason (R) provided in the question.

### Step 1: Understanding Assertion (A)
The assertion states: "If the speed of a particle is never zero, then it may have zero average speed."

- Average speed is defined as the total distance traveled divided by the total time taken.
- If the speed of a particle is never zero, it implies that the particle is always moving and covering some distance.
- Therefore, if the particle is always moving, the distance traveled cannot be zero, which means the average speed cannot be zero.

**Conclusion for Assertion (A)**: The assertion is **false** because if the speed is never zero, the average speed cannot be zero.

### Step 2: Understanding Reason (R)
The reason states: "The average speed of a moving object in a closed path is zero."

- A closed path means that the object returns to its starting point.
- While the displacement (the shortest distance from the initial to the final position) is zero in a closed path, the distance traveled is not zero.
- The average speed is calculated based on the total distance traveled, not displacement. Hence, the average speed cannot be zero if the object has traveled a distance.

**Conclusion for Reason (R)**: The reason is also **false** because the average speed of an object in a closed path is not zero; it is based on the total distance traveled.

### Final Conclusion
Both the assertion (A) and the reason (R) are false. Therefore, the correct answer is that both statements are incorrect.
