A vertical spring is attached to the floor, as shown in Figure 1. An object of mass m_(1) is placed on top of the spring and slowly lowered, compressing the spring a distance x_(1) from its unstretched length, until it reaches equilibrium, as shown in Figure 2. Next, an object of mass m_(2) is placed on top of the first object and slowly lowered, compressing the spring an additional distance x_(2). The system is again in equilibrium in Figure 3 . Which of the following correctly relates x_(2) to x_(1) ? x_(2)=((m_(1)+m_(2))/(m_(1)))x_(1) (D) x_(2)=((m_(2)-m_(1))/(m_(1)))x_(1)
