A) 1
B) 0.5
C) 4
D) 4
Correct Answer: A
Solution :
Frequency \[n=2\pi \sqrt{\frac{T}{m}}\] \[n=2\pi \sqrt{\frac{T}{\pi {{r}^{2}}l\rho }}\] \[n=2\pi \sqrt{\frac{T}{\pi {{r}^{2}}l\rho }}\] \[n\propto \sqrt{\frac{T}{r}}\] \[\frac{{{n}_{1}}}{{{n}_{2}}}=\sqrt{\frac{{{T}_{1}}}{{{T}_{2}}}}\frac{{{r}_{2}}}{{{r}_{1}}}\] \[=\sqrt{\frac{4}{1}}\times \frac{1}{2}\] \[=\frac{2}{1}\times \frac{1}{2}=1\]You need to login to perform this action.
