Problem

Consider a system consisting of two oppositely charged spheres hanging by strings and separated by a distance r1, as shown in the accompanying illustration. Suppose they are separated to a larger distance r2, by moving them apart along a track.

Two oppositely-charged particles are hanging by strings.  In the first diagram, the particles are pulled toward each other, separated by distance r1.  In the second diagram, they hang straight down, separated by the larger distance r2.

What effect, if any, does this process have on the value of E?
