The magnitude of frequency response of an underdamped second-order system is 5 at 0 rad/sec and peaks at \(\frac{10}{\sqrt{3}}\) at 5√2 rad/sec. The transfer function of the system is
1
\(\frac{{245}}{{\left( {{s^2} + 1.21s + 49} \right)}}\)
2
\(\frac{375}{s^2+5 s+75}\)
3
\(\frac{500}{s^2+12 s+100}\)
4
\(\frac{1125}{s^2+25 s+225}\)
