A train is moving with a constant speed along a large circular track. The engine of the train
\( P \) emits a sound of frequency \( f \). The frequency heard by the guard at rear end of the train :
W
(1) is less than \( f \)
(2) is greater than \( f \)
(3) is equal to \( f \)
(4) may be greater than, less than or equal to \( f \) depending on the factors like speed of train, length of train and radius of circular track
