A) less than\[f\]
B) equal to\[f\]
C) is greater than\[f\]
D) 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
Correct Answer: B
Solution :
Suppose v be the speed of sound. Then \[v={{v}_{o}}={{v}_{s}}\] and \[f=f\left( \frac{v+{{v}_{o}}\cos \theta }{v+{{v}_{s}}\cos \theta } \right)\] \[=f\left( \frac{v+v\cos \theta }{v+v\cos \theta } \right)=f\]You need to login to perform this action.
