The equation of a wave on a string of linear mass density \( 0.04 \mathrm{~kg} \mathrm{~m}^{-1} \) is given by
\( \mathrm{P} \) \( y=0.02(m) \sin \left[2 \pi\left(\frac{t}{0.04(s)}-\frac{x}{0.50(m)}\right)\right] \). The tension in the

W string is
[AIEEE 2010]
(a) \( 6.25 \mathrm{~N} \)
(b) \( 4.0 \mathrm{~N} \)
(c) \( 12.5 \mathrm{~N} \)
(d) \( 0.5 \mathrm{~N} \)
