Gauss’s law: charge and a cube
Place a charge at the centre, a face, an edge or a corner of a cube and find the flux through it.
What to notice
A charge on the surface is shared: only the fraction of field lines that enter the cube count.
Key relation
Φ = q_enclosed / ε₀
Try this
Move the charge from the centre to a corner. What fraction of q/ε₀ passes through the cube?
What you can change
- Charge q: -10 to 10 nC
- Charge position: choose Centre of cube, Centre of a face, Middle of an edge, A corner
