The relationship between the force applied to a spring and the displacement it causes is given by Hooke's Law, which states that the force is directly proportional to the displacement. Since the springs are identical and the weight on spring B is 1.5 times the weight on spring A (18 N compared to 12 N), the displacement caused by the weight on spring B will also be 1.5 times the displacement caused by the weight on spring A. Therefore, if spring A is displaced by 2 cm, spring B will be displaced by 2 cm * 1.5 = 3 cm.

Spiral Springs a and B Are Identical
