The mass suspended from the stretched string of a sonometer is 4 kg and the linear mass density of string 4 xx 10^(-3) kg m^(-1) . If the length of the vibrating string is 100 cm , arrange the following steps in a sequential order to find the frequency of the tuning fork used for the experiment . (A) The fundamental frequency of the vibratinng string is , n = (1)/(2l) sqrt((T)/(m)). (B) Get the value of length of the string (l) , and linear mass density (m) of the string from the data in the problem . (C) Calculate the tension in the string using , T = mg . (D) Substitute the appropriate values in n = (1)/(2l) sqrt((T)/(m)) and find the value of 'n' . |

Answer» BCAD `m = 4 xx 10^(-3) kg m^(-1)` (b) T = mg = `4 xx 9.8 = 39.2`N (c) Consider , the fundamental frequency of the vibration STRING is n , = `(1)/(2l) sqrt((T)/(m))` (a) SUBSTITUTE the values of l , T and m in n = `(1)/(2l) sqrt((T)/(m))` and calculate the VALUE of n and this frequency of tuning fork (d) . |
