SUMMARY
The electric flux through a face of a cube with a point charge +Q at its center is calculated using the formula Flux = Q/ε. The total electric flux emanating from the charge is Q/ε, and since the cube has six faces, the flux through each face is Q/(6ε). However, the correct answer for the flux through one face, considering symmetry and distribution, is Q/(4ε). This discrepancy arises from the application of Gauss's Law, which dictates that the flux through one face is a quarter of the total flux due to the geometry of the cube.
