Two tuning forks, \( A \) and \( B \), produce notes of frequencies \( 258 \mathrm{~Hz} \) and \( 262 \mathrm{~Hz} \). An unknown note
P sounded with \( A \) produces certain beats. When the

W same note is sounded with \( B \), the beat frequency gets doubled. The unknown frequency is
(a) \( 250 \mathrm{~Hz} \)
(b) \( 252 \mathrm{~Hz} \)
(c) \( 254 \mathrm{~Hz} \)
(d) \( 256 \mathrm{~Hz} \)
