A string of $7 m$ length 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:

Given : Length $(l) = 7 m$ $Mass (M) = 0.035 kg$ and tension $(T) = 60.5$ $N$ . We know that mass of string per unit length $(m)$ $= \frac{0.035}{7} = 0.005 kg / m$ and speed of $wave = \frac{T}{m} = \frac{60.5}{0.005} = 110 m / s .$
