Two strings are tuned to the same pitch (184 Hz). Later you increase the tension in one string. Now, when both strings are played, there are 2 beats every second. What is the new frequency of the string that was tuned?

186 Hz

Explanation:

We know,velocity of a wave="frequency"xx lamda
also, velocity =sqrt(Tension//mu)
now,if i increase the tension in one of them,velocity increases and consequently the frequency becomes higher,
thus,the value of the new frequency will be greater than 184Hz.
we know,n_1~n_2="beat" " frequency"
plugging in the values,.
n_1=184+2 or 186Hz
