Do my HW part 45

[Jon Miller]

I get -100% for handwriting fairly often (when I am right damnit)

I have only once had an anal bastard reject my work due to handwriting.

On an Algebra III assignment that took me 10 hours, no less.

[Jon Miller]

that is horrid

I have to agree though, my HW is bad (he only takes off 100% for the problem, he has threatened to just reject my assignments though)

who is currently spending a minute on HW for every 5 on apolyton

[Jon Miller]

heyt Frogger (or anyone else)

what is a boss?

I am suppose to work with a boss on a plane conductor

Jon Miller

[KrazyHorse]

Just a bump. I bet you it's a hemispherical bump of radius "a"...

[Jon Miller]

yah

but in or out?

JHon Miller

[KrazyHorse]

They have to tell you that.

[Jon Miller]

probably out...

Jon Miller

[Jon Miller]

hmm

if it is out

and you had a point charge right above this bump on the conductor

where would yuo place image charges (that is what I am thinking to use)?

I was thinking of just usning the plane, and the sphere placements

but that doesn't seem right

Jon Miller

[KrazyHorse]

The question is what? charge density on surface of conductor?

[Jon Miller]

yah

Jon Miller

[KrazyHorse]

That should work. The "hole" in the conducting plane is okay since the plane image charge method works for finite conducting planes as well...

[Jon Miller]

no, on the bump

Jon Miller

[Jon Miller]

ok, hmm, wonder why it is not coming out

thanks

Image charges always seemed like hoodoo to me.

Just make sure that the resulting image charge configuration gives you the right boundary condition on the conducting plane (i.e. that V is constant on the surface)...
