Assertion: There is no apprecible change in the position of the body during the action of the impulsive force.
Reason: In case of impulsive force the time of action of the force is very short.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true and reason is the not correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Explanation

To solve the assertion-reason question, we will analyze both the assertion and the reason step by step.

### Step 1: Analyze the Assertion
**Assertion:** There is no appreciable change in the position of the body during the action of the impulsive force.

- An impulsive force is defined as a force that acts for a very short duration of time.
- During this short duration, the displacement of the body is minimal because the time interval is so brief that the body does not move significantly.
- Therefore, the assertion is correct: there is indeed no appreciable change in the position of the body during the action of the impulsive force.

### Step 2: Analyze the Reason
**Reason:** In case of impulsive force, the time of action of the force is very short.

- This statement is also correct. The defining characteristic of an impulsive force is that it acts over a very short time interval.
- Because the time of action is short, the force can change the momentum of the body without causing a significant displacement.
- Hence, the reason correctly explains why the assertion is true.

### Step 3: Conclusion
Both the assertion and the reason are correct, and the reason provides a valid explanation for the assertion. Therefore, we conclude that:

- **Both the assertion and reason are true, and the reason is the correct explanation of the assertion.**

### Final Answer:
Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
