Expert Answer:

Dear student
Following is the detailed working out of your query:
Take r as the radius fo each ring & R is the distance of separation between the two centers of the rings.
Work done in moving a unit charge from the cneter of ring 1 to the center of ring 2 will be
W = V2 - V1
So substitute & transpose the terms, we obtain the following expression:
We hope that clarifies your query
