Flux Through Face of Tetrahedron

[physicsphreak2]

Homework Statement

Suppose a point charge is placed on the face of a regular tetrahedron. What is the flux through another one of the faces?

Homework Equations

The Attempt at a Solution

I know that if the charge is placed at the center of the tetrahedron, the flux through any face would simply be q/(4*ε) since each face gets an equal share of the total flux.

But since the charge is placed on one of the faces, I would think that each other face sees q/(6*ε) of flux? Since "half the total flux" simply doesn't go through the tetrahedron at all, and the half that does is shared equally with a third going to each remaining face?

Is this valid?

That sounds right to me as long as the point charge is placed at the center of one of the faces.

Definitely yes.
