A unity feedback second order control system is characterised by \(\mathrm{G}(s)=\frac{\mathrm{K}}{s(\mathrm{~J} s+\mathrm{B})}\)
where \(\mathrm{J}=\) moment of inertia, \(\mathrm{K}=\) system gain, \(\mathrm{B}=\) Viscous damping coefficient. The transient response specification which is NOT affected by variation of system gain is the:
(a) peak overshoot
(b) rise time
(c) settling time
(d) damped frequency of oscillations
