In figure (A), mass 2m2m2m is fixed on mass mmm which is attached to two springs of spring constant kkk. In figure (B), mass mmm is attached to two spring of spring constant kkk and 2k2k2k. If mass mmm in (A) and (B) are displaced by distance xxx horizontally and then released, then time period T1{T}_{1}T1​ and T2{T}_{2}T2​ corresponding to (A) and (B) respectively follow the relation.
