A wire having tension 225 N produces six beats per second when it vibrates with some tuning fork. When the tension changes to 256 N, it vibrates with the same fork with the number of beats remaining unchanged. The frequency of the fork will be
Text Solution
Verified by ExpertsThe correct answer is:
A
For wire vibrating under tension, the fundamental frequency is given by 
, Where T is tension and 
, linear mass density of string
It is given that, when it is sounded with a tuning fork of frequency 
beats per second were heard
undefined
