Homework Statement
A point charge of 20 nC is located at (4,-1,-3), and a uniform line charge of -25nC/m lies along the intersection of the planes x=-4 and z=6. (a) Calculate D at (3,1,0). (b) How much electric flux leaves the surface of a sphere of radius 5, centered at the origin? (C) Repeat part b if the radius of the sphere is 10.
Homework Equations
Q=total flux enclosed
The Attempt at a Solution
I've already solved part a without a problem but its b and c that are giving me trouble. I seem to be having problems with Gauss's law. A sphere of radius 5 seems like it would enclose the 20nC point charge so wouldn't electric flux simply equal 20 nC. The answer seems to be 0 though.
