The transverse displacement of a string (clamped at its both ends) is given by
\( \mathrm{P} \)
\[
y=0.06 \sin \left(\frac{2 \pi}{3} x\right) \cos (120 \pi t)
\]
W
where \( \mathrm{x} \) and \( \mathrm{y} \) are in \( \mathrm{m} \) and \( \mathrm{t} \) is in \( \mathrm{s} \). The length of the string is \( 1.5 \mathrm{~m} \) and its mass is \( 3.0 \times 10^{-2} \mathrm{~kg} \), then tension in string is :-
(1) \( 648 \mathrm{~N} \)
(2) \( 650 \mathrm{~N} \)
(3) \( 649 \mathrm{~N} \)
(4) \( 651 \mathrm{~N} \)
