Flux

[ookt2c]

1. The problem statement, all variables and given/known data
Evaluate the flux of F(x,y,z)=xi + yj + zk across the surface q:x^2+y^2+z^2=16, oriented by unit normals.


2. Relevant equations


3. The attempt at a solution

[HallsofIvy]

One: I don't see any attempt at a solution- just integrate!

Two: Since there are no bounds to the surface it looks to me like the flux will be infinite. Weren't there any boundaries given?

Three: You have copied the problem incorrectly. "Oriented by unit normals" makes no sense. There are two unit normals at a point of any surface. The orientation is given by choosing one of them. Oriented by which unit normal?
