Three tuning forks A, B and C have respective frequencies \( n_1, n_2 \) and \( n_3 \) related as \( n_1 = 1.03n_2 \) and \( n_3 = 0.99n_2 \). When A and C are sounded together 4 beats are heard per second. The frequencies of fork B and C are respectively
Show Hint
- Beats = frequency difference
- Convert % relation into algebra before solving
