    A tuning fork produce 2 beats when sounded with one oscillator of frequency 514 Hz, and produces 6 beats with the other oscillator of frequency 510 Hz. The frequency of tuning fork is

    A) 516 Hz                                  

    B)  510 Hz

    C)  514 Hz                                 

    D)  520 Hz

    Correct Answer: A

    Solution :

    Tuning fork produces 2 beats with oscillator of 514 Hz. \[\therefore \]Frequency of tuning fork \[{{n}_{1}}=514\pm 2\] =516 or 512 Hz Similarly, \[{{n}_{2}}=510\pm 6=514\text{ }or\text{ }504\text{ }Hz\] \[\therefore \] Frequency of tuning fork = 516 Hz
