A spring mass system is held at rest at height H from the ground with the spring in relaxed state. Find the minimum value of H so that the sytem has a tendency to rebound after hitting the ground. (Here mass `m_(2)` is stick with ground after collision i.e. between `m_(2)` and ground perfect inelastic collision)

A

`(m_(2)g)/K((2m_(1)+m_(2))/(2m_(1)))`

B

`(m_(2)g)/(2K)((2m_(1)+m_(2))/(2m_(1)))`

C

`(m_(2)g)/K`

D

`((2m_(1)+m_(2))/(2m_(1)))`
