If the length of a stretched string is shortened by `40 %` and the tension is increased by `44 %`, then the ratio of the final and initial fundamental frequencies is

If the length of a stretched string is shortened by 40 % and the tension is increased by 44% then ratio of the final and initial fundamental frequencies is

If the length of a stretched string is shortened by x% and the tension is increased by 44%. Then the ratio of the final and initial fundamental frequencies is 2:1 , then the value of x is

The fundamental frequency of a sonometer wire increases by 6 Hz if its tension is increased by 44 % , keeping the length constant . Find the change in the fundamental frequency of the sonometer wire when the length of the wire is increased by 20 % , keeping the original tension in the wire constant.

The linear density of a stretched string is increased by 1%. Then the change in fundamental frequency of string is
