D. 1,2
Answer:B
The characteristic equation of a system is given ass3+25s2+10s+50=0. What is the number of the roots in the right half s-plane and the imaginary axis respectively?
A. 1,1 B. 0,0 C. 2,1 D. 1,2
Explanation: The characteristic equation has no sign changes so number of roots on the right half of s plane is zero.
