Solution

The correct option is D Pressure difference
As high speed moving train drags the air with it, at a high speed, the dynamic pressure near the train increases.
By the Bernoulli's principle, the local static pressure near the train goes down, and high pressure region pushes the person towards the train, where static pressure is low.
So pressure difference causes such effect.

A person standing near the track of a fast moving train has a tendency to fall towards it because of:

A train running at 108 km $h^{- 1}$ towards east whistles at a dominant frequency of 600 Hz. Speed of sound in air is 340 m/s. What frequency will a passenger sitting near the open window hear ? (b) What frequency will a person standing near the track hear whom the train has just passed ? (c) A wind starts blowing towards east at a speed of 36 km $h^{- 1}$ . Calculate the frequencies heard by the passenger in the train and by the person standing near the track.
