The Fig. 87 shows a critically damped spring-mass system undergoing single degree of freedom vibrations. If \(m=5 \mathrm{~kg}\) and \(k=20 \mathrm{~N} / \mathrm{m}\), the value of viscous damping coefficient is

(a) \(10 \mathrm{Ns} / \mathrm{m}\)

(b) \(20 \mathrm{Ns} / \mathrm{m}\)

(c) \(4 \mathrm{Ns} / \mathrm{m}\)

(d) \(8 \mathrm{Ns} / \mathrm{m}\).
