A string \( 1 \mathrm{~m} \) long is drawn by a \( 300 \mathrm{~Hz} \) vibrator attached to its end. The string vibrates in 3 segments. The speed of transverse waves in the string is equal to
\( \mathrm{P} \)
(A) \( 100 \mathrm{~m} / \mathrm{s} \)
(B) \( 200 \mathrm{~m} / \mathrm{s} \)
(C) \( 300 \mathrm{~m} / \mathrm{s} \)
(D) \( 400 \mathrm{~m} / \mathrm{s} \)
