The frequency of a tuning fork $A$ is 2% more than the frequency of a standard tuning fork. The frequency of the same standard tuning fork. If 6 beats $s^{- 1}$ are heard when the two tuning fork $A$ and $B$ are excited, the frequency of $A$ is

(a) Let the frequency of standard fork $= x$
$	herefore n_{A} = \frac{102}{100}x,\ \ n_{B} = \frac{97}{100}x$
Number of beats $s^{- 1} = n_{A} - n_{B} = 6$
$\frac{102}{100}x - \frac{97}{100}x = 6$
$x = \frac{6 	imes 100}{5} = 120\ Hz$
