Two stretched strings A and B when vibrated together produce 4 beats per second. If the tension applied to the string A increased, the number of beats produced per second is increased to 7. If the frequency of string B is 480 Hz initially. The frequency of string A is
- A 473 Hz
- B 476 Hz
- C 484 Hz
- D 487 Hz
Answer & Solution
Correct Answer
(C) 484 Hz
Step-by-step Solution
Detailed explanation
\(\mathrm{n}_{\mathrm{A}} \sim \mathrm{n}_{\mathrm{B}}=4\) Now, if tension in string A increased, then frequency of string A increased and beats produced increased.…
