Question
Only need to do part b) and c)
For part a I found the electric field to be:
E = -z(phi)/2*pi*e_0 (1/z - 1/(R^2 + z^2)^1/2))
Transcribed Image Text:(a) Find the electric field a distance z above the center of a flat circular disk of radius R, which
carries a uniform surface charge density o.
Z
P
R
(b) Without doing the calculation, state what the electric field should look like (i.e. what kind of
system) in the limit of R→ ∞. Check your intuition by calculating the electric field in the limit
of R→∞.
(c) Without doing the calculation, state what the electric field should look like (i.e. what kind of
system) in the limit of z » R. Check your intuition by calculating the electric field in the limit of
z » R.
