C. Add extra weight to keep the rope tightly stretched
D. To keep the Centre of gravity always vertically
Answer
Correct Answer: D. To keep the Centre of gravity always vertically
Detail about MCQs
The correct answer is:
D. To keep the Centre of gravity always vertically
Explanation:
The long pole carried by a tightrope walker helps to:
Lower the center of gravity: By holding the pole, the walker increases their moment of inertia, making it harder to topple.
Stabilize balance: The pole helps the walker make small adjustments to counterbalance any tilt, ensuring the center of gravity remains aligned over the rope for stability.
This technique is crucial for maintaining equilibrium while walking on the tightrope.
