A particle with charge Q is located immediately above the center of the flat face of a hemisphere of radius R as shown in the figure below.
(a) What is the electric flux through the curved surface? (Use any variable or symbol stated above along with the following as necessary: ε0.)
(b) What is the electric flux through the flat face? (Use any variable or symbol stated above along with the following as necessary: ε0.)
Gauss's Law states
The Integral of (E)dot(dA) = qenclosed/Epsilon0
The Attempt at a Solution
I'm not sure what the picture is stating with the symbol that I suppose goes to 0. But from my understanding the point is outside the surface or so I thought and the flux would be 0 but that is wrong. So I thought that the flux given out is Q/Epsilon0 for the curved surface, but apparently it's not enclosed either. I'm not sure what I'm missing. It's probably something simple.
