To increase the frequency from 100 Hz to 400 Hz the tension in the string has to be changed by
Text Solution
Verified by ExpertsThe correct answer is:
B
$n \propto \sqrt{T}$
$\therefore \frac{T_1}{T_2} = \frac{n_1^2}{n_2^2} = \left(\frac{100}{400}\right)^2 = \frac{1}{16}$
$\Rightarrow T_{2} = 16 T_{1}$
