0A metal bar clamped at its centre resonates in its fundamental mode to produce longitudinal waves of frequency \( 4 \mathrm{kHz} \). Now the clamp is moved to one end. If \( f_{1} \) and \( f_{2} \) be the frequencies of first overtone and second overtone respectively then,
(1) \( 3 f_{2}=5 f_{1} \)
(2) \( 3 f_{1}=5 f_{2} \)
(3) \( f_{2}=2 f_{1} \)
(4) \( 2 f_{2}=f_{1} \)
