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 \[v={{v}_{0}}={{v}_{s}}\] and \[f=f\left( \frac{v+{{v}_{0}}\cos \theta }{v+{{v}_{s}}\cos \theta } \right)\] \[=f\left( \frac{v+v\cos \theta }{v+v\cos \theta } \right)=f\]You need to login to perform this action.
