0A vibrator makes \( 150 \mathrm{~cm} \) of a string to vibrate in 6 loops in the longitudinal arrangement when it
\( \mathrm{P} \) is stretched by \( 150 \mathrm{~N} \). The entire length of the
W string is then weighed and is found to weigh \( 400 \mathrm{mg} \). Then select incorrect statement:-
(1) Fundamental frequency of the string is \( 250 \mathrm{~Hz} \)
(2) Frequency of the vibrator is \( 1.5 \mathrm{kHz} \).
(3) distance between two nodes is \( 25 \mathrm{~cm} \)
(4) distance between two anti nodes is \( 12.5 \mathrm{~cm} \)
