A single degree of freedom mass-spring - viscous damper system with mass $$m,$$ spring constant $$k$$ and viscous damping coefficient $$q$$ is critically damped. The correct relation among $$m, k$$ and $$q$$ is

$$q = \sqrt {2km} $$

$$q = 2\sqrt {km} $$

$$\,q = \sqrt {{{2k} \over m}} $$

$$q = 2\sqrt {{k \over m}} $$
