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 ________. (Round off to the Nearest Integer)
