A) is less than f
B) is greater than f
C) is equal to 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: C
Solution :
Let V = speed of sound and u = speed of train Then, \[{{V}_{S}}={{V}_{0}}=u\] and \[F=F\left( \frac{V+{{V}_{0}}\,\cos \theta }{V+{{V}_{s}}\,cos\theta } \right)\] \[=F\,(as\,{{V}_{0}}={{V}_{S}})\]You need to login to perform this action.
