A man standing close to the platform at a railway station experiences a pulling force towards a fast moving train because of ________ .

A. Gravitational force between train and man

B. Illusion of the man

C. The centripetal force

D. Pressure difference due to fast moving air in between

Answer: Option D

Solution (By Examveda Team)

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.
