The discussion centers on calculating the electric field strength given that 50 pJ of energy is stored in a 2.0 cm x 2.0 cm x 2.0 cm region of a uniform electric field. The relevant formula for electric field energy is derived from the relationship between energy (U), electric field strength (E), and volume (V). The electric field strength can be determined using the equation U = (1/2) * ε * E² * V, where ε is the permittivity of the medium. The participants suggest consulting the Wikipedia page on electric fields for further insights.
