For a particular measurement application, an accelerometer must be selected with a bandwidth or useful frequency range of \(5,000 \mathrm{~Hz}\). If the allowable deviation in the scaling coefficient \(C_{A}=\frac{1}{\sqrt{\left(1-r^{2}\right)^{2}+(2 \zeta r)^{2}}}\) is \(\pm 1 \%\) and the damping ratio is known to be 0.65 , determine the minimum required for the natural frequency of the accelerometer.
