1. Consider a charge \(q\) located at the corner of a cube. Find the electric flux through the side shaded in grey.

    Function

    Consider a larger cube composed of eight of these smaller cubes shown, with \(q\) at the centre. The electric flux through this large cube will be \(q/\epsilon_0\). The indicated side is 1/24 the area of the total cube, so it has flux \(\Phi_E = q/24\epsilon_0\) through it.
