Question

19 A string oscillating at fundamental frequency under a tension of
225N produces 6 beats/sec with a sonometer If the tension is 256N,
then again oscillating at fundamental note it produces 6beats per
second with the same sonometer The frequency of the sonometer is
----------

Suppose the frequency of sonometer is n
Initially frequency of the string is less than that of the sonometer
So, n-k225=6or n-6=k225=15 k--(i)In second case, frequency of string is more, thusn+6=k256=16 k---(ii)From (i) and (ii),n-6n+6=1516or n=186 Hz
