If vibration of string is to be two times, then tension in the string must be made

Options:

Answer:

Solution:

Here: Initial vibration $n_{1} = n$ , final vibration $n_{2} = 2 n$ Initial tension $T_{1} = T$ Vibration of frequency of string $n = \frac{1}{2 l} \frac{T}{m}$ $\Rightarrow n \propto T$ Hence, $\frac{n _{1}}{n _{2}} = \frac{T _{1}}{T _{2}}$ or $\frac{T _{1}}{T _{2}} = (\frac{n _{1}}{n _{2}})^{2} = (\frac{n}{2 n})^{2} = \frac{1}{4}$ or $T_{2} = 4 T_{1}$
