Consider a particle of mass $$m$$ with a total energy $$E$$ moving in a one dimensional potential field. The potential $$V(x)$$ is plotted against $$x$$ in the figure beside. The plot of momentum-position graph of this particle is qualitatively best represented by. All plots are symmetrical about the $$x$$-axis.
