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: Option C
Explanation
(frac{f}{256} = sqrt{frac{196}{100}})
f = (sqrt{frac{256^2 times 196}{100}})
= 356.4Hz
