A 0.0145 kg, 1.92 m long wire is fixed at both ends and vibrates in its simplest mode under a tension of 193 N. When a tuning fork is placed near the wire, a beat frequency of 5.20 Hz is heard. What are the possible frequencies of the tuning fork? B)What should the tension in the wire be if the beats are to disappear? for part A i have calcuated u=7.55e-3 and velocity along the string which is v=159 m/s what i am thinking of doing is the following: i know my beat freq. is 5.20 Hz. I also know that Freq.b = Delta w/2pi i am thinking of rearanging to find w and then pluging everything into: F= 1/2pi * srt w that may give me one frequency of the tunning frok and then from here i take the frequency from my answer and then minus my beat frequency from it giving me my other frequency. Is this what i have to do?? and for B) im not really sure how to approach it any hints?
