Two stretched wires A and B of same material vibrate independently. If the tension, length and radius of wire B is half those of wire A, then ratio of fundamental frequency of vibration of A and B is

The length , radius , tension and density of string A are twice the same parameters of string B . Find the ratio of fundamental frequency of B to the fundamental frequency of A .

A musical instrument is made using four different metal strings, 1, 2, 3 and 4 with mass per unit length mu,2mu,3mu and 4mu respectively. The instrument is played by vibrating the strings by varying the free length in between the range L_0 and 2L_0 . It is found that in string-1 (mu) at free length L_0 and tension T_0 the fundamental mode frequency is f_0 . List-I gives the above four strings while list-II lists the magnitude of some quantity. If the tension in each string is T_0 , the correct match for the highest fundamental frequency in f_0 units will be -
