Statement - I One end of ideal massless spring is connected to fixed vertical wall and other end to a block of mass m initially at rest on smooth horizontal surface. The spring is initially in natural length. Now a horizontal force F acts on block as shown. Then the maximum extension in spring is equal to maximum compression in spring.
Statement - II To compress or to expand an ideal unstretched spring by equal amount, same work is to done on spring.
