A tunig fork whose frequency as given by mufacturer is `512 Hz` is being tested with an accurate oscillator it is found that the fork produces a beat of 2 Hz when oscillator reads 514 Hz but produces a beat of 6 Hz when oscillator reads 510 Hz. The actual frequency of fork is

508 Hz

512 Hz

516 Hz

518 Hz

Text Solution

Verified by Experts

The correct Answer is:
