Rank in order, from most to least, the elastic potential energy ${\left(U_{s_p}\right)}_{a}to{\left(U_{S_p}\right)}_d$stored in the springs of FIGURE $Q10.5$Explain.

The energy accumulated as a result of applying a force to deform an elastic item is known as elastic potential energy. The energy is retained until the force is withdrawn, at which point the item returns to its original shape and does work. The object could be compressed, stretched, or twisted as a result of the deformation.

When we compress or lengthen a stretched spring, we experience a force equivalent to the force we apply in the opposite direction. However, as soon as the stress is relieved, the spring returns to its original shape. The spring potential energy is what it's called. When a spring is squeezed or stretched, the spring's potential energy increases in both circumstances. This is due to the fact that we work in both compression and stretching.

Therefore, most to least elastic potential energy of spring in the given figure is$d>c>a>b.$
