Homework Statement
An uncharged nonconductive hollow sphere of radius 19.0 cm surrounds a 20.0 µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. Calculate the electric flux through the hole.
Homework Equations
Volume charge distribution = Q/V
Flux = q/ε0 = EA
The Attempt at a Solution
So I started off by finding the Volume which was (4/3)pi(0.19^3) = 0.0287
I then divided the charge by this to get the Volume Charge Density = 6.9686^-4
Here is where I get stuck. I have no idea how to relate the Volume Charge Density to the flux through the small hole. I thought perhaps I should find the Area Charge Density of the small hole but I am really unsure. I am not asking for the answer, I just need a brief description of where to go from here/ what formulas to use. Any help would be greatly appreciated!
