Question

An engine is moving on a circular track with a constant speed. It is blowing a whistle of frequency $500 blank H z.$ The frequency received by an observer standing stationary at the centre of the track is

$500 H z$
More than $500 H z$
Less than $500 H z$
More or less than $500 H z$ depending on the actual speed of the engine

The correct answer is: $500 blank H z$

Since there is no relative motion between the source and listener, so apparent frequency equals original frequency
