Spring With Low Spring Constant. E = 15 cm = 0.15 m. As per the hooke’s law, if spring is stretched, the force exerted is proportional to the increase in length from the equilibrium.

The product of spring constant and length remains constant. Web when a spring is cut into two halves of equal length, the spring constant of each half doubles. This gives exactly how much force is required to deform any spring of any material.
