A spring is suspended with a weight of $2.0\,\text{N}$ attached, and this causes an extension of $6.0\,\text{cm}$. The $2.0\,\text{N}$ weight is then taken away, and an $8.0\,\text{N}$ weight is hung from the spring instead. The spring does not go beyond its limit of proportionality. What is the spring's new extension?
- A$6.0\,\text{cm}$
- B$24\,\text{cm}$
- C$36\,\text{cm}$
- D$48\,\text{cm}$
