Homework Statement
Hi. A cylinder of radius r & length L whose charge density distribution is given by
ρ = C/2 * r3
where r = radial distance in cylindrical coordinates
C = constant
show that the average charge density ρbar = a3 C / 5
Homework Equations
Gauss differential law div E = ρ / ε0
div E = 1/r * ∂/∂r * (rEr) + 1/r ∂E∅/∂∅ + ∂Ez/∂z
The Attempt at a Solution
Hmmm! Not really sure where to begin with this.
Not sure if it's to do with stuff as "difficult" as equations above.
