0 out of 1 points The characteristic equation of a closed-loop control system is given as \( \mathrm{s}(\mathrm{s}+2)(\mathrm{s}+6)+\mathrm{K}=0 \) where \( \mathrm{K} \) is a real number. Calculate the value of \( \mathrm{K} \) when two roots lie on the imaginary axis. Write the numeric answer below. Keep two decimal places. No unit is needed. Correct Answer: \( \quad 96.00 \pm 10 \% \)
