A string of length ' \(\ell\) ' fixed at one end carries a mass 'm' at the other end. The string
makes \(\frac{3}{\pi}\) revolutions / second around the vertical axis through the fixed end as
shown in figure. The tension 'T' in the string is
- A \(36 \mathrm{~m} \ell\)
- B \(3 \mathrm{~m} \boldsymbol{\ell}\)
- C \(9 \mathrm{~m} \ell\)
- D \(18 \mathrm{~m} \ell\)
Answer & Solution
Correct Answer
(A) \(36 \mathrm{~m} \ell\)
Step-by-step Solution
Detailed explanation
\(\omega=\frac{3}{\pi} \varepsilon p s=6 \mathrm{rad} / 8 .\)
\(T=m \omega^{2} \ell\)
\(=36 m .\)
