A body of mass `m` is attached by an inelastic string to a suspended spring of spring constant `k`. Both the string and the spring have negligible mass and the string is inextensible and of length `L`. Initially, the mass `m` is at rest.  Q. If the mass `m` is now raised up to point `A` (the top end of the string see fig. and allowed to fall from rest, the maximum extension of the spring in the subsequent motion will be
