The ﬁgure below shows a graph of potential
energy versus interatomic distance for a particular molecule. Rank the magnitude of the
force at locations A, B, and C. (That is, which
is the greatest, which is smallest, and are any
of these equal to each other?)

F = -dU/dx ?
The Attempt at a Solution
To be honest I really have no idea on this one :/. I thought I could find the force using the change of potential energy corresponding with change in interatomic distance but that does not give me the right answer.
It would seem more logical to calculate force based on R itself. Since it's interatomic, I assume force increased with decreasing R, but again that was wrong.
EDIT: Never mind. I realized my mistake and I did not read the "magnitude" word in the question. I figured out the right answer so this thread is no longer needed
