The open loop transfer function G(s) of a unity feedback control system is given as, G(s) = \binom{k (s +\frac{2}{3}) }/{s^{2}(s + 2)} From the root locus, it can be inferred that when k tends to positive infinity.

Correct Answer is : three roots with nearly equal real parts exist on the left half of the s-plane

three roots with nearly equal real parts exist on the left half of the s-plane

one real root is found on the right half of the s-plane

the root loci cross the jω axis for a finite value of k; k ≠ 0

three real roots are found on the right half of the s-plane

The open loop transfer function G(s) of a unity feedback control system is given as,

G(s) = \;{k\;(s\;+\;{2}/{3})\;}/{s^{2}(s + 2)}

From the root locus, it can be inferred that when k tends to positive infinity.
