A mass m is vertically suspended from a spring of negligible mass, the system oscillates with a frequency n. what will be the frequency of the system, if a mass 4 m is suspended from the same spring? A mass m is vertically suspended from a spring of negligible mass if a mass 4 m [...]

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 [...]
