Question
Two sitar strings A and B playing the note ′Ga′ are slightly out of tune and produce beats of frequency 6 Hz. The tension in the string A is slightly reduced and the beat frequency is found to reduce to 3 Hz. If the original frequency of A is 324 Hz, what is the frequency of B?
Options
A.316 Hz
B.318 Hz
C.330 Hz
D.324 Hz
Solution
According to Q. frequency of B may be 318 Hz or 330 Hz. As no. of beat decreases if tension in the string A (i.e. frequency) is reduced so nB = 318 Hz
