A force of 1N is required to stretch a spring by 1.5cm. If the spring is cut into three equal parts, find the force required to stretch one part by 3 cm.

20 J work is required to stretch a spring through 0.1 m. Find the force constant of the spring If the spring is further stretched through 0.1 m, calculate work done

One end of a spring is kept fixed while the other end is stretched by a force as shown in the diagram. Name one instrument which works on the above principle.

What will be the force constant of the spring system shown in figure?

Two springs are in a series combination and are attached to a block of mass 'm' which is in equilibrium. The spring constants and extension in the springs are as shown in the figure. Then the force exerted by the spring on the block is :
