Consider the points s1 = −3 + j4 and s2 = −3 − j2 in the s-plane. Then, for a system with the open loop transfer function $$G\left(s\right)H\left(s\right)=\frac K{\left(s+1\right)^4}$$$A s1 is on the root locus, but not s2 B s2 is on the root locus, but not s1 C both s1 and s2 are on the root locus D neither s1 nor s2 is on the root locus 4 GATE ECE 1992 MCQ (Single Correct Answer) +2 -0.6 Given a unity feedback system with open loop transfer function, $$G\left(s\right)=\frac K{s\left(s+1\right)\left(s+2\right)}$$$ The root locus plot of the system is of the form.
