The frequency of tuning fork \( \mathrm{A} \) is \( 2 \% \) more than the frequency of a standard tuning fork.
\( \mathrm{P} \)
The frequency of a tuning fork B is \( 3 \% \) less
W than the frequency of same standard tuning fork. If 6 beats per second are heard when the two tuning forks \( \mathrm{A} \) and \( \mathrm{B} \) are excited, the frequency of \( \mathrm{A} \) is :-
(1) \( 120 \mathrm{~Hz} \)
(2) \( 122.4 \mathrm{~Hz} \)
(3) \( 116.4 \mathrm{~Hz} \)
(4) \( 130 \mathrm{~Hz} \)
