Answer:
8 s
Explanation:
Damping factor, F is given by
[tex]F=\frac {1}{2Q}[/tex] where Q is quality factor
Also, we know that the settling time, T is given by
[tex]T=\frac {4}{FW}[/tex] where W is the resonant frequency.and substituting the first equation here we get
[tex]T= \frac {4\times 2Q}{W}[/tex]
Since it takes 2% of final value to settle and considering 100 rad/s for resonant frequency and taking quality factor of 100 then
[tex]T=\frac {4\times 2\times 100}{100}= 8 s[/tex]
