A) \[\frac{v}{2}\]
B) \[3v\]
C) \[2v\]
D) \[v\]
Correct Answer: D
Solution :
By using \[v=v\left[ \frac{v-{{v}_{0}}}{v-{{v}_{s}}} \right]\] \[2v=v\left[ \frac{v-{{v}_{0}}}{v-0} \right]\] \[\Rightarrow \] \[{{v}_{0}}=-v.\] Negative sign indicates that observer is moving opposite to the direction of velocity of sound.You need to login to perform this action.
