A tuning fork A of frequency as given by the manufacturer is 512 Hz is being tested using an accurate oscillator. It is found that they produce 2 beats per second when the oscillator reads 514 Hz and 6 beats per second when it reads 510 Hz . The actual frequency of the fork in Hz is (510+x) . Calculate the value of x .

Correct answer

6

Step-by-step solution

For 1^ st reading of oscillator aligned & f_A=(514 2) Hz & f_ A =516 ~Hz or 512 ~Hz aligned For 2^ nd reading of oscillator f_A=(510 6) H z f_A=516 ~Hz or 504 Hz A has a frequency of 516 Hz
