it takes 10 J of energy to move 2 C of charge from point A to point B. How large is the potential difference between points A and B

Ok so what we need to find is how large is the potential difference between points A and B.

Now you make a statement about what this potential difference would do in this problem

We now know that the points from A and B relies to transport a difference by using points A to B per unit change.

=5 V (5 volt).
