Uniformly distributed electric field lines

Click For Summary
SUMMARY

The discussion centers on the distribution of electric field lines when a positive charge is placed at the center of a cube. It concludes that while the electric field lines emanate from a point charge, they are not parallel and thus do not represent a uniformly distributed electric field across the sides of the cube. The definition of "uniformly distributed" in this context refers to the equal density of field lines across a surface, which is not achieved in this scenario due to the radial nature of the field lines from a point charge.

Homework Statement



A positive charge is placed in the center of a cube. Are the intersections of the field lines with a side of the box uniformly distributed across that side. Explain.

===

I have missed some lectures due to getting the swine flu (ugh) and the material is not exactly clear on this, but all problems that describe a uniform electric field are shown with parallel lines all coming from one side. I could see the answer being either yes, it's uniform, because all the lines are coming from a point charge in the center of the box, but the lines are not parallel. So, what is the definition of "uniformly distributed"?

Just missing a fundamental definition...
