The frequency `n_(1), n_(2) and n_(3)` of three tuning forks A, B, C are related as
`n_(1) = 10.2 n_(2) and n_(2) = 0.97 n_(2)`
When A and C are sounded together, 5 beats/second are heard. What is the frequency of the fork A?

A

100 Hz

B

102 Hz

C

110 Hz

D

98 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(1) gt n_(3) and n_(1) - n_(3) = 5`
`:. 1.02 n_(2) - 0.97 n_(2) = 5`
`:. n_(2) = 100 Hz and n_(1) = 102 Hz`
