There are three identical springs (the same original length, the same spring constant).
Two objects with mass ma and mb (ma=mb initlially) are attached at both end (supported by two bars).
What will happened if those two bars were removed at the same time?

1. Two objects oscillate symmetryly at both side.
2. The object at left side will oscillate with larger amplitude than object at the right side.
3. The object at right side will oscillate with larger amplitude than object at the left side.
4. The object at the left side will move down, while the object at the right side will move up.
5. The object at the right side will move down, while the object at the left side will move up.
