A conservative force acts on a particle...

A conservative force acts on a particle as the particle moves along the positive x-axis from origin origin to `x=2m`. The force is parallel to x-axis. Now, consider four different cases, as shown in the figures, 1, 2, 3, and 4, where the forces is shown as a function of x. Rank the situations according to the change in potential energy associated with the force, least ( or most negative) to greatest ( or most positive).
