A mass is suspended separately by two springs of spring constant k1​ and k2​ in successive order. The time periods of oscillations in the two cases are T1​ and T2​ respectively. If the same mass be suspended by connecting the two springs in parallel (as shown in figure) then the time period of oscillations is [...]
