A spring lies along the x-axis attached to a wall at one end and a block at the other end. The block rests on a friction less surface at x = 0. A force of constant magnitude F is applied to the block that begins to compress the spring, until the block comes to a maximum displacement
xmax.
During the displacement, which of the curves shown in the graph best represents the work done on the spring block system by the applied force?
