According to Hooke's Law, the displacement of a spring is proportional to the force applied to it. Therefore, if we double the weight (force) suspended from the spring, we will double the displacement (distance) the spring stretches. Hence, the ratio of the displacement for the new weight to the displacement for the original weight will be 2:1, or a factor of 2.
