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 HzYou need to login to perform this action.
