Which of the lettered graphs below might also legitimately describe the potential energy for the same interaction (between the same two particles!) whose potential energy function is shown in the "original" graph in the upper left? In each case, the vertical axis is energy (increasing upward) and that axis crosses the horizontal axis where $r=0$ .
