Springs A and B are used in a door-closing mechanism. A force of 4.0 N is applied to each spring without exceeding either spring's limit of proportionality.
The table shows the extension of each spring.
| Spring | Extension in m |
|---|---|
| A | 0.020 |
| B | 0.050 |
Which spring is stiffer?
The springs have the same stiffness
The stiffness cannot be determined without the original lengths
Spring B
Spring A
