Review Conceptual Example 7 as background for this problem. A positive
charge +91 is located to the left of a negative charge -92. On a line passing
though the two charges, there are two places where the total potential is zero.
The first place is between the charges and is 4.16 cm to the left of the negative
charge. The second place is 7.57 cm to the right of the negative charge. (a) What
is the distance between the charges? (b) Find 91/92, the ratio of the magnitudes
of the charges.
