Consider two identical springs each of spring constant \( k \) and negligible mass compared to the mass \( M \) as shown. Figure \( 1 \) shows one of them and Figure \( 2 \) shows their series combination. The ratio 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)
