A string of length $7 m$ has a mass of $0.035 kg$ . If tension in the string is $60.5 N$ , then speed of a wave on the string is

Options:

Answer:

Solution:

speed of a wave on the string is,

$v = \sqrt{\frac{T}{μ}}$

Linear mass density is, $μ = \frac{0.035}{7}$

$μ = 5 \times 1 0^{- 3} kg / m$

$∴$ $v = \sqrt{\frac{60.5}{5 \times 1 0^{- 3}}}$

$v = \sqrt{12.1 \times 1 0^{3}}$

$v = 110 m / s$
