Her motion involves moving back and forth along the straight road (rectilinear motion) while also repeatedly covering the same path, indicating a periodic pattern. The combination of both rectilinear and periodic aspects characterizes Paheli's motion in this scenario. Understanding the interplay between these types of motion is fundamental in physics studies.

Understanding Paheli's Motion
Paheli's motion can be analyzed based on two key characteristics: rectilinear motion and periodic motion.
1. Rectilinear Motion
- Definition: Rectilinear motion refers to movement along a straight line.
- Paheli's Path:
- She moves from point A to point C via points AB and BC in a straight line.
- Upon returning from C to A, she again follows the same straight path (CB and BA).
- Conclusion: Since all her movements occur along a straight line, her motion is classified as rectilinear.
2. Periodic Motion
- Definition: Periodic motion is defined as motion that repeats itself after a certain interval of time.
- Paheli's Rounds:
- Paheli makes 5 continuous rounds along the same path from A to C and back to A.
- Each complete round (A to C and back to A) takes a consistent amount of time.
- Conclusion: Since the motion repeats after each round, it qualifies as periodic.
Final Analysis
- Combined Motion: Since Paheli's movement is both along a straight line (rectilinear) and repeats over time (periodic), her motion is classified as both types.
- Correct Answer: Therefore, the correct answer is option 'C' - Rectilinear and periodic both.
In summary, Paheli's movement showcases characteristics of both rectilinear and periodic motion, making her overall motion a combination of both types.
