Homework Statement
A charged rod with uniform charge per length and total charge Q is placed along the z-axis with one end at the origin. The rod is located on the positive z-axis according the the diagram accompanying the problem (not shown). Find the electric field E(x,0,0) at any point...
ive already posted this is another bit of the forums, and only just noticed the Electronic Engineering section!
My boyfriend is doing a dgree in electronic engineering and is studying fields and devices at the moment and is really stuck so i was wondering if anyone could help!
His notes...
hey
just looking for some help on an electric field question involving a rod of charge. here's the problem:
You have a charge, Q, uniformly distributed along a thin, flexible rod with length L. The rod is then bent into a semi-circle.
a) Find expression for electric field at center of...
I've been having trouble with this one for a while, and I know where I'm stuck. Here's the problem:
There's a uniformly charged rod of length "L" along the x axis. There is also a point on the x-axis that is a distance of "a" away from the end of the rod. So the whole thing looks kind of like...

I used the equation:
kq/(d(d+L))
I converted everything to meters before doing the calculations. (I'm kind of pressed for time at the moment... i'll post the actual work in 2 hours.)
I want to make sure the equation is right.
Hi I was just wondering what the answer to the following question would be:
If you bring a positively charged rod to an uncharged electroscope causing the vanes or leaves inside to diverge, are negative charges attracted to the knob of the electroscope or do positive charges repel to the...
Ok really stuggling with this, and this is the last in the set
lets say there's a rod on the Y and there is a test charge Q located a distance D from the rod on the 45degree line that bisects the x and y axes. (that is the line f(x) = x, identity function) Write an equation in vector...
Ok, I'm inexperienced with the latex code, so excuse me.
I'm trying to derive the expression for the electric field at a point, along the perpendicular bisector of a charged rod, of known total charge, length L, a perpendicular distance y from the rod.
The horizontal components cancel...
