The Nyquist plot of a conditionally stable system is shown below for a specific gain K. Move the dot in the figure to the first loop on the uaxis near the origin. (a) Determine whether the system is stable and find the number of roots (if any) in the right-hand s-plane. The system has no poles of Gc(s)G(s) in the right half-plane. (b) Determine whether the system is stable if the -1 point lies at the dot on the axis
