- Homework Statement
- The non uniform electric field through a cube is given by E= 3xi^+4j^. We need to find flux of a surface of a Gaussian cube. The surface that we need to find for is at x= 3 meter.

- Relevant Equations
- Phi= int of(vector E. vector dA)

Phi = int of (3xi^ + 4j^).vector dA = 3 int of(xdA)

Now we put x= 3 and we get at last 36 N m^2/C.

I am getting confused why E is a fuction of x. How can that be? How can we represent the E and position x on the same coordinate system. Is it right ? Because we know distance is inversely proportional to E. how is it multiplied like that?
