(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The electric field inside a circular cylinder of radius r = a and height z = h is given by: E = Az[(-c/h)+(b/6(epislon zero)*(3z^2 - h^2)

where c and b are constants. Assuming the medium within the cylinder is free-space, find the total charge enclosed within the cylinder.

2. Relevant equations

Qtot = int(int(D*ds)) = int(int(int(rho*dv)))

D = epsilon*E

3. The attempt at a solution

Surface integral of each side (1-top, 2-side, 3- bottom)

1 & 3 = 0

2 = h*pi*r^3

not sure what to do from here?

***Nevermind, I figured it out I think. I'll post the solution if anybody wants it.
