The total electric flux through a cube when charge 8q is placed at one corner of the cube

Question

Professor PC Thomas Classes · Answer

When a charge is placed at a corner of a cube, it can be imagined as being at the center of a larger cube formed by 8 identical cubes. The total flux through this larger cube is $\frac{8q}{\epsilon_0}$, so the flux through each cube is $\frac{q}{\epsilon_0}$.
