Hey all,
I'm working on some homework for my electromagnetics class...
I'm having a hard time understanding it all, and I'm hoping someone can help me out.

Right now we are dealing with point charges, electromagnetic fields, potential.

If anyone has a good website for this stuff I would greatly appreciate it.

one of the problems is, Q1 is at (4,0,3) Q2 @ (2,0,1) if q2 = 4nc, find q1 so that A): E @ (5,0,6) has no Z component. B): Force on a test charge at (5,0,6) has no x component.

My strategy for this is to find the E field at (5,0,6) from Q2, then take the neg value of the z component and use that to solve for Q1.

I think you are heading in the right direction. A 3 dimensional plot would make the problem clear.
