we find the value of \(T_2\)
\(T_2 = m_2w^2l_2\)
and find \(T_1\) so
\(T_1 = m_2w^2l_2 + m_2w^2l_1\)
The we find the ratio of \(T_1\) and \(T_2\)
\(T = mg \frac{T_1}{T_2}\)
\(= \frac{m_2w^2l_1 + m_2w^2l_2}{m_2w^2l_2}\)
we can get the expression
\(\frac{T_1}{T_2} = \frac{\left[m_1 + m_2\frac{l_2}{l_1}\right]l_2}{m_2l_2}\)
\(\frac{T_1}{T_2} = \frac{(m_1 + 2m_2)}{2m_2}\)
we can say that
\(\frac{T_1}{T_2} = \frac{(m_1 + 2m_2)}{2m_2}\)
