Consider two identical springs each of spring constant $k$ and negligible mass compared to the mass $M$ as shown. Fig. 1 shows one of them and Fig. 2 shows their series combination. The ratios of time period of oscillation of the two SHM is $\frac { T _ { b } } { T _ { a } } = \sqrt { x }$, where value of $x$ is $\_\_\_\_$.\\
