Homework Statement
The circular region, ρ < a, z= 0, carries a uniform surface charge density ρ ( subscript s). Find E at P(0,0,h), h > 0.
Homework Equations
Coulombs law
Field of a line charge and field of a sheet charge.
The Attempt at a Solution
I'm not sure what they are asking for , but my attempt I used the equation for a field of a sheet of charge cause it's the only one provided in the Homework that contains the ρ (subscript s).
It says E at point (0,0,h) so I'm guessing since its at z = 0 then the vector would be (0,0,h-0). Resulting in my result of
E = (ρ(subscript s) / 2ε ) (0,0,h)
Im not really sure what I'm supposed to be finding
