The frequency of fork A is 3% more than ...

The frequency of fork A is 3% more than the frequency of a standard fork where as the frequency of fork B is 3% less. The fork A and B produce 6 beats per second. The frequency of standard fork will be -

A

100 Hz

B

103 Hz

C

106 Hz

D

112 Hz

Text Solution

Verified by Experts

The correct Answer is:
A
`n_(A) = n + (3n)/(100), n_(B) = n - (3n)/(100)`
`:. n_(A) - n_(B) = (6n)/(100)`
`:' n_(A) - n_(B) = 6 :. (6n)/(100) = 6 :. n = 100 Hz`
