In the diagram shown below, both the strings $A B$ and $C D$ are made of same material and have same cross-section. The pulleys are light and fictionless. If the speed of wave in string $A B$ is $v_{1}$ and in $C D$ is $v_{2}$ , then $\frac{v _{1}}{v _{2}}$ is

Options:

Answer:

Solution:

Let the speed of wave in string be $v$ and tension in string be $T$ . $v \propto T \frac{v _{A B}}{v _{C D}} = \frac{T}{2 T} = \frac{1}{2}$
