SUMMARY

The "w" in the equation represents the energy density of an electrostatic field, defined as w = (epsilon_0)(E^2). Here, epsilon_0 denotes the permittivity of free space, and E represents the electric field strength. This equation illustrates the relationship between electric field intensity and energy storage in electrostatic fields, providing a foundational concept in electromagnetism.
