1. The problem statement, all variables and given/known data One end of a string of mass 1.45 g and length 50.0 cm is attached to a frequency generator and the other end to a weight holder which hangs over a fixed pulley . The part of the string between the generator and the pulley is horizontal . THe string is set to vibrate . Several weights are added until a fundamental frequency of 120 Hz is achieved . Calculate the tension in the string when the fundamental frequency is achieved . 2. Relevant equations 3. The attempt at a solution f=v/2L 120=v/(2 x0.05) v=120 m/s not really sure whether this is even an attempt . I do not know how to link the v i got here to tension in the string .
