A tuning fork of known frequency \( 256 \mathrm{~Hz} \) makes 5 beats per second with the vibrating string of a piano. The beat frequency decreases to 2 beats per second when the tension
\( \mathrm{P} \) in the piano string is slightly increased. The frequency of the

W piano string before increasing the tension was
[AIEEE 2003; CBSE PMT 2010]
(a) \( 256+5 \mathrm{~Hz} \)
(b) \( 256+2 \mathrm{~Hz} \)
(c) \( 256-2 \mathrm{~Hz} \)
(d) \( 256-5 \mathrm{~Hz} \)
