A) \[2:1\]
B) \[4:1\]
C) \[8:1\]
D) \[1:1\]
Correct Answer: D
Solution :
Fundamental frequency \[v=\frac{1}{2l}\,=\frac{1}{2l}\,\sqrt{\frac{T}{\pi {{r}^{2}}\rho }}\,or\,v=\frac{1}{2lr}\] \[\frac{{{v}_{1}}}{{{v}_{2}}}=\,\frac{{{l}_{2}}{{r}_{2}}}{{{l}_{1}}{{r}_{1}}}\,=\frac{2L\times r}{L\times 2r}\,=1\]You need to login to perform this action.
