In a guitar, two strings A and B made of same material are slightly out of tune and produce beats of frequency $\displaystyle 6$ Hz. When tension in B is slightly decreased, the beat frequency increases to $\displaystyle 7$ Hz. If the frequency of A is $\displaystyle 530$ Hz, the original frequency of B will be :
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 524$ Hz
