The frequencies of two tuning forks `A` and `B` are respectively `1.5%` more `2.5%` less than that of tuning fork `C`. When `A` and `B` sounded together, 12 beats are produced in `1` second. The frequency of tuning fork `C` is

The frequecies of tuning forks A and B are respectively 5% more and 3% less than the frequency of tuning fork C. When A and B are sounded together 8 beats/second are heard. Then the frequency of the tuning fork B will be

The frequency 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

The frequency of tuning forks A and B are respectively 5% more and 4% less than the frequency of tuning fork C. When A and B are simultaneously excited, 9 beats per second are produced. Then the frequency of the tuning fork A (in Hz) is

The frequency of tuning forks A and B are respectively 5% more and 4% less than the frequency of tuning fork C. When A and B are simultaneously excited, 9 beats per second are produced. Then the frequency of the tuning fork A (in Hz) is

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

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 sonometer wire resonates with a tuning fork. It itslength isincreased by 5%,10 beats are produced per second. The frequency of the tuning fork is.

A tuning fork vibrates with 2 beats in 0.04 second. The frequency of the fork is

In a closed tube when air column is 20cm it is in resonance with tuning fork A. When the length is increased by 2cm then the air column is in resonance with tuning fork B. When A and B are sounded together they produce 8 beats per second . The frequencies of the tuning forks A and B are (in Hz)
