A block placed on a smooth horizontal floor is connected to a spring as shown. Initially an external f orce of 100N keeps it stretched by 1 cm beyond natural lenght in equilibrium. The force is now removed and another force and another force F is applied on this block,which slowly moves it from this position to a position where the spring is finally compressed by 3 cm. Find the work done by this force F(in joules)
