The correct Answer is:
To determine the direction of the centripetal force required to move a body along a circular path, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Circular Motion**: When a body moves in a circular path, it is constantly changing its direction. This change in direction requires a force to act on the body. 2. **Inertia of Direction**: According to Newton's first law of motion, an object in motion will continue to move in a straight line unless acted upon by an external force. If no force is applied, the body would move in a straight line due to its inertia. 3. **Need for Centripetal Force**: To keep the body moving in a circular path, a force must be applied towards the center of the circular path. This force is known as centripetal force. 4. **Direction of Centripetal Force**: The centripetal force always acts towards the center of the circular path. This is essential for changing the direction of the velocity of the body, allowing it to follow the circular trajectory. 5. **Conclusion**: Therefore, the direction of the centripetal force is always directed towards the center of the circular path. ### Final Answer: The direction of the centripetal force will be towards the center of the circular path. ---
