Two vibrating strings of the same material but lengths `L` and `2L` have radii `2r` and `r` respectively. They are stretched under the same tension. Both the string vibrate in their fundamental nodes, the one of length `L` with freuqency `v_(1)` and the other with frequency `v_(2)`. the ratio `v_(1)//v_(2)` is given byA. 2B. 4C. 8D. 1 |

Answer» Correct Answer - D `n_(1)=(1)/(2l) sqrt([(T)/(4 pi r^(2) rho)])` and `n_(2) =(1)/(4 l) sqrt([(T)/(pi r^(2) rho)])` `:. (n_(1))/(n_(2)) = 2xx (1)/(2) =1`. |
