If the frequency of the tuning fork at resonance is 256Hz, calculate the frequency of vibration of the wire when the tension in he wire is increased to 196N
- A. 130.6Hz
- B. 182.9Hz
- C. 358.4Hz
- D. 501.8Hz
Correct Answer: C. 358.4Hz
Explanation
\(\frac{f}{256} = \sqrt{\frac{196}{100}}\)
f = \(\sqrt{\frac{256^2 \times 196}{100}}\)
= 356.4Hz
