A force of 20.0 N is required to hold a spring stretched by 5.0 cm from its equilibrium position. How much work was done in stretching the spring ?

When a force of 0.1 N is applied a spring is stretched by 1.5 cm. The spring is cut into three parts and one part is stretched by 3 cm. The force required for this is

A spring 40 mm long is stretched by the application of a force. If 10 N force required to stretch the spring through 1mm, then the work done in stretching the spring through 40 mm is

A spring 40 mm long is stretched by the application of a force. If 10 N force required to stretch the spring through 1mm, then the work done in stretching the spring through 40 mm is

It work done positive or negative for stretched spring ?

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.
