An experiment is carried out to measure how the length of a spring changes as different weights are hung from it.
The table below shows the results of the experiment:
| Weight / N\text{N}N | Length / mm\text{mm}mm |
|---|---|
| 0 | 340 |
| 2.0 | 348 |
| 4.0 | 356 |
| 6.0 | 365 |
| 8.0 | 373 |
What is the extension of the spring when the weight hung from it is 6.0 N?
9 mm9\text{ mm}9 mm
17 mm17\text{ mm}17 mm
25 mm25\text{ mm}25 mm
365 mm365\text{ mm}365 mm
