Question

A wire having a linear mass density 9.0 10^-4 kg/m is stretched between two rigid supports with a tension of 900N. The wire resonates at a frequency of 500Hz. The next higher frequency at which the same wire resonates is 550Hz. The length of the wire is .....m

Accepted Answer

Correct answer: 10. (10) =9.0 10^-4 kgm T=900N V= T = 9009 10^-4= 1000ms f_1=500Hz f=550 nV2l=500….(i) (n+1)V2l=500 …(ii) (ii) (i) V2l=50 l= 10002 50=10
