A transverse wave is propagating on the string. The linear density of a vibrating string is $10^{- 3} k g / m .$ The equation of the wave is $Y = 0.05 \sin (x + 15 t),$ where, $x$ and $Y$ are in metre and time in seconds. The tension in the string is

Options:

Answer:

Solution:

$∵ v = \sqrt{\frac{T}{μ}}$
$\frac{ω}{k} = \sqrt{\frac{T}{μ}}$
$\frac{15}{1} = \sqrt{\frac{T}{10^{- 3}}}$
$∴ T = 225 \times 10^{- 3} \Rightarrow T = 0.225 N$
