The freuquency of tuning forks A and B are respectively `3%` more and `2%` less than the frequency of tuning fork `C`. When A and B are simultaneously excited, 5 beats per second are produced. Then the frequency of the tuning fork `A` (in Hz)` Is

A

`98`

B

`100`

C

`103`

D

`105`

Text Solution

Verified by Experts

The correct Answer is:
C

Let frequency of `C : x`
`f_(A) =1.03x, f_(B) =0.98x`
`1.03x - 0.98x = 5 rArr x = 100 Hz`
`f_(A) = 1.03x = 103 Hz`
