Uniformly distributed electric field lines

AI Thread Summary
A positive charge placed at the center of a cube generates electric field lines that radiate outward. While the lines originate uniformly from the charge, they are not parallel, which complicates the definition of "uniformly distributed" across the cube's sides. The concept of uniform distribution typically refers to equal spacing and directionality of field lines, which is not the case here. Therefore, the intersections of the field lines with a side of the box are not uniformly distributed. Clarifying the definition of uniform distribution in the context of electric fields is essential for understanding this concept.

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...

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
