Assertion (A): A slight change in pole-zero configuration can cause only minor changes in root locus configuration.

Reason (R): Asymptotes show the behaviour of root loci for |s| >> 1

  • A.Both A and R are correct and R is correct explanation of A
  • B.Both A and R are correct but R is not correct explanation of A
  • C.A is correct but R is wrong
  • D.R is correct but A is wrong

Answer: D

Even a slight change in pole-zero position may affect root locus appreciably.
