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