Answer:
(a) 25%
Explanation:
It is given that damping ratio [tex]\zeta =0.4[/tex]
The maximum peak overshoot [tex]M_P[/tex] is given by [tex]M_P=e^\frac{-\pi \zeta }{\sqrt{1-\zeta ^2}}[/tex]
So [tex]M_P=e^\frac{-3.14\times 0.4}{\sqrt{1-0.4^2}}=0.2538=25.28[/tex] % which is nearly equal to the 25 % so the option (a) will be the correct option as in option (a) it is given that maximum peak overshoot is 25%
