Question

A charge q is placed at the corner of a cube of side a. The electric flux through the cube is:

G1 Physics · Accepted Answer

Step 1: Arrange eight identical cubes around the common corner so the charge lies at the centre of the larger cube. Step 2: Total flux through larger cube = q/ε₀. Step 3: Symmetry divides flux equally among eight cubes, giving q/(8ε₀).
