Q. A man standing close to the platform at a railway station experiences a pulling force towards a fast moving train because of ________
✅ Correct Answer: (D)
Pressure difference due to fast moving air in between
Explanation: When a fast-moving train passes a man standing on the platform at rest, the air between train and person also moves with greater speed. This rapidly moving air, by Bernoulli's principle will have a lower pressure than the still air a few feet away.
