Question
Chapter 10, Problem 20Q
To determine
To Explain:The children are advised to stand away from the rapidly moving train because they might get sucked under it.
Expert Solution & Answer
Explanation of Solution
Introduction:
When a high-speed object moves, it creates a low-pressure region. This low-pressure region causes a suction force on the near by objects.
Due to the high speed of the train it creates a low-pressure region near it.The air farther than the train and air near to the train has a high-pressure difference. This difference in pressure results in a suction force towards the train, which could pull a lightweight object towards the train.Thus, it is possible that if children stand near a running train, they might be sucked under it.
Conclusion:
Because of the pressure difference,a suction force induces which could push a light-weight objects towards the train.
