Okay, I've checked the integral for p, and it works, and I can appreciate how this condenses to a dipole field, since the rod and dipole would look the same given enough distance.
So that means I'm trying to condense Erod to the form E=c*k*p/d3, c being a numerical multiplier, correct?
Homework Statement
A thin rod of length 2L has a linear charge density that isλ0 at the left end but decreases linearly with distance going from left to right in such a way that the charge on the entire rod is zero.
Given
E = −kλ0/L(d/(L−d)−ln(d−L)+d/(L+d)+ln(L+d))
for a point P that is...
I switched some numbers around in my second post, so it screw some more things up. I think it's supposed to be:
0.05=|d2-(d2+0.013)|/(d2+0.013)
in which case it gives d=0.501m,
which is wrong.
Well... I could probably compare the radii for both. In which case, I would have:
0.05 = |d2-(d2+0.013)|/d2
0.05=0.013/d2
d=0.51 m
Am I on the right track there?
Homework Statement
You wish to determine the electric field magnitude along the perpendicular bisector of a 230-mm line along which35 nC of charge is distributed uniformly. You want to get by with a minimal amount of work, so you need to know when it is sufficient to approximate the line of...
Homework Statement
A positively charged particle initially at rest on the ground accelerates upward to 180 m/s in 2.70 s .The particle has a charge-to-mass ratio of 0.100 C/kg and the electric field in this region is constant and uniform.
What are the magnitude and direction of the electric...
