Four identical point charges, each with charge \(q\), are initially positioned infinitely far apart. In Scenario 1, the charges are brought together and held fixed at the four vertices of a regular tetrahedron with edge length \(a\). In Scenario 2, the same four charges are brought together and held fixed at the four vertices of a square with side length \(a\). What is the ratio of the work required to assemble Scenario 1 to the work required to assemble Scenario 2, \(W_1 / W_2\)?
