The OLTF of the unity feedback control system is as given below:
\(G\left( s \right) = \frac{k}{{s\left( {s + 2} \right)\left( {s + 3} \right)}}\). If the value of ‘k’ is kept at the maximum value, the closed-loop system will oscillate at a frequency of ‘a’ rad/sec then the value of \(\frac{{62a}}{{(a/\sqrt6) + k}}\) is
