354980 In a guitar, two strings \(A\) and \(B\) made of same material area slightly out of tune and produce beats of frequency \(6Hz\). When tension in B is slightly decreased, the beat frequency increase to \(7 Hz\). If the frequency of \(A\) is \(530\;Hz\), the original frequency of \(B\) will be:

1 \(524\;Hz\)
2 \(536\;Hz\)
3 \(537\;Hz\)
