A sonometer wire is resonating with a tuning fork of frequency N. If its length is increased by 10% , by keeping the tension constant , 6 beats are heard per second, then

`N = 60 ` Hz

` N = 66` Hz

` N = 54` Hz

` N = 72 ` H z

Text Solution

Verified by Experts

The correct Answer is:

`n_(1)/n_(2) = l_(2)/l_(1) = 11/10 :. n_(1) = 11/10 n_(2)`
`:. n_(1) - n_(2) = 6 " " :. n_(2) = 60`
` :. n_(1) = N = 60 + 6 = 66 ` Hz
