Statement-I : When the direction of motion of a particle moving in a circular path is reversed the direction of radial acceleration still remains the same (at the given point).
Statement-II : Particle revolves on circular path in any direction such as clockwise or anticlockwise the direction of radius accelerationis always towards the centre of the circular path.

Options

A. Statement-I is true, Statement-II is true, Statement-II is correct explanation for Statement-I
B. Statement-I is true, Statement-II is true, Statement-II is NOT a correct explanation for Statement-I
C. Statement-I is true, Statement-II is false
D. Statement-I is false, Statement-II is true.

Answer

To solve the question, we need to analyze both statements provided and determine their validity.

### Step-by-Step Solution:

1. **Understanding Radial Acceleration**:
- Radial acceleration (also known as centripetal acceleration) is the acceleration directed towards the center of a circular path. It is responsible for changing the direction of the velocity of the particle moving in a circular motion.

2. **Analyzing Statement-I**:
- Statement-I claims that when the direction of motion of a particle moving in a circular path is reversed, the direction of radial acceleration still remains the same at the given point.
- Regardless of the direction of motion (clockwise or counterclockwise), the radial acceleration always points towards the center of the circular path. Therefore, if the particle reverses its direction, the radial acceleration will still point towards the center.
- **Conclusion**: Statement-I is correct.

3. **Analyzing Statement-II**:
- Statement-II states that a particle revolving on a circular path in any direction (clockwise or anticlockwise) has its radial acceleration always directed towards the center of the circular path.
- This is a fundamental property of circular motion; the radial acceleration is always directed towards the center, irrespective of the direction of motion.
- **Conclusion**: Statement-II is also correct.

4. **Relationship Between the Statements**:
- Statement-II provides a clear explanation for Statement-I. Since both statements are true and Statement-II explains why Statement-I is true, we can conclude that both statements are correct and related.

### Final Conclusion:
- Both Statement-I and Statement-II are true, and Statement-II is the correct explanation for Statement-I.
