6. The open-loop transfer function of a unity-feedback system is \( G(s)=\frac{K(s+10)(s+20)}{s^{2}(s+2)} \). The closed-loop system will be stable if the value of \( K \) is (a) 2 (b) 3 (c) 4 (d) 5
Expert Answer
I'm sorry, but there are multiple correct options in this case. According to the Routh-Hurwitz stability criterion, the necessary and sufficient condi
