Flux through a hole in a sphere??? I have worked on this for a while and need some help. Answers or hints are appericated A 6:1 uC charge located at the origin of a cartesian coordinate system is surrounded by a nonconducting hollow sphere of radius 9:1 cm. A drill with a radius of 1:02 mm is aligned along the z axis, and a hole is drilled in the sphere. Calculate the electric flux through the hole. Answer in units of N/m(sqd)=C.
