A block of mass `m` collides with another block of mass `3m` completely inelastically as shown in figure. What is the maximum value of `v (` in `m//s)` for which the block `B` does not move. Assume that initially spring is in natural length and blocks `A` and `B` are at rest. `(K//m=100 S.I. `unit `)`
