of negligible mass, spring constant k and unstretched length L. First, one spring is attached to the end of the other spring and slowly lowered to its equilibrium position. The two spring stretch a total distance of X1. Next the spring are hung side by side. The block is attached to the end of the springs and again slowly lowered to its equilibrium position. The springs each stretch a distance of X2. Which of the following correctly shows the relationship between x1 and x2?
(a) X1=X2
(b)X1=â2X2
(c)X1=2X2
(d)X1=4X2
(e)X1=8X2
