Question

If one of the arms of a tuning fork is broken then its frequency of vibration is :

• A. not effected
• B. less than before
• C. as before
• D. more than before

Answer 1

The correct option is A not effected

The frequency of a tuning fork is inversely proportional to the square of the length of the prongs. So if one arm is broken then also fork will have same length of prongs as one prong is still standing unaffected . So frequency is not effected.

answer is A.
