A. 10
B. 20
C. 30
D. 40
Answer:B
The characteristic equation of a control system is s(s2+ 6s+13)+K=0. The value of k such that the characteristic equation has a pair of complex roots with real part -1 will be :
A. 10 B. 20 C. 30 D. 40
Explanation: The characteristic equation is considered and the values of G and w are calculated and further the value of k can be calculated.
