Question

A string is producing transverse vibration whose equation is $y = 0.021 sin (x + 30 t)$ , where $x$ and $y$ are in meters and $t$ is in seconds. If the linear density of the string is $1.3 \times 1 0^{- 4}$ kg/m, then the tension in the string in N will be:

Options:

Answer:

D

Solution:

$v = ω / k = 30/1 = 30$ m/s. $T = μ v^{2} = 1.3 \times 1 0^{- 4} \times 900 = 0.117$ N.
