Consider two identical springs each of spring constant kk and negligible mass compared to the mass MM as shown. Fig. 11 shows one of them and Fig. 22 shows their series combination. The ratios of time period of oscillation of the two SHM is TbTa=x,\dfrac{{T}_{b}}{{T}_{a}} = \sqrt{x}, where value of xx is ______.

(Round off to the Nearest Integer)

Consider two identical springs each of spring constant k and negligible mass compared to the mass M as shown. Fig. 1

Correct answer

0

Step-by-step solution

Ta=2πMK{T}_{a} = 2\pi\sqrt{\dfrac{M}{K}}

Tb=2πMK/2{T}_{b} = 2\pi\sqrt{\dfrac{M}{K / 2}}

TbTa=2=x\dfrac{{T}_{b}}{{T}_{a}} = \sqrt{2} = \sqrt{x}
