A) \[246\text{ }Hz\]
B) \[250\text{ }Hz\]
C) \[254\text{ }Hz\]
D) \[242\text{ }Hz\]
Correct Answer: C
Solution :
By the question, \[|250-{{V}_{B}}|=4\] \[{{V}_{B}}\] can be \[254\text{ }Hz\] or \[246\text{ }Hz\] Now on filling of A, \[{{V}_{A}}\] will increase and on waxing of B, \[{{V}_{B}}\] will decrease, For same number of beats initially, \[{{V}_{B}}>{{V}_{A}}\] \[{{V}_{B}}=254\,Hz\]You need to login to perform this action.
