Question:

The value of \( k \), where root locus cuts the jω axis in plotting root locus, is calculated by

Show Hint

The jω crossing in root locus is found using the condition \( \frac{dK}{ds} = 0 \).

The Correct Option is A

Solution and Explanation

On the root locus, the point where it crosses the jω-axis is the point where \( \frac{dK}{ds} = 0 \). This condition helps in identifying the breakaway or entry points on the imaginary axis.
