Question

find the continuous charge distribution for a disk of a charge?(assume charge to be positive)

Answer 1

do you have specific dimensions or are you referring to a derivation?

Answer 2

am referring to a derivation

Answer 3

Charge distribution or electric field?

Answer 4

yeah electric field due to a circular disk of charge

Answer 6

there is a fairly standard derivation that can be found all over the place. are you just looking for a resource or do you want to talk through it? either way is cool.

Answer 7

I found it to be real nice. If you want for Infinite sheet, then it can be easily done using Gauss' Law.

Answer 8

what if i used the coulumb's law? would i get the answer?

Answer 9

start with coulombs law, that is all there really is. the rest is calculus and geometry.

Answer 10

The link I posted uses Coulomb's law. Check out the Electric field due to ring, and then you can get the 'due to sheet'. But, honestly, Coulomb's law shall be tedious, as there is symmetry for infinite sheet.

Answer 11

Ok i got it the electric field due to a ring of charge is E=1/4\[\pi \].qz/(r^2 +z^2)^3/2 i have to use this eq then put the value of surface charge density and start with the calculas

Answer 12

Yes, but don't memorize it. Understand the derivation.

Answer 13

i got my answer thnx guys i'll fan u both :D
