A particle is to move along the `x-`axis from `x=0` to `x=x_(1)` while a conservative force, directed along the `x-`axis, acts on the particle. For each force defination presented in the figures the maximum magnitude of the force `(F_(1))` is the same for all cases. Rank the forces according to the change in potential energy associated with the motion shown. from most positive to most negative`:`
