The work required to assemble eight identical charged particles, each with charge q, at the corners of a cube with side length a is calculated using the formula W = k * q^2 * Σ(1/r_ij), where k is Coulomb's constant and r_ij is the distance between each pair of charges. In this configuration, the total work amounts to 28kq^2/a, indicating that the system is not stable due to the repulsive forces acting between the like charges. Therefore, any slight displacement will lead to an increase in potential energy, making the configuration unstable.
