Two strings, A and B, have respective mass densities µA and µB respectively. The linear mass density, pB, of string-B is nine times that of string-A (µB = 9µA). If both strings have the same fundamental frequency when kept at the same tension, then the ratio of their lengths LA / LB is equal to: O 1/9 O 9 3 O 1/3 Two strings, A and B, have respective mass densities µA and µB respectively.
