Can someone please help me work through this problem I've spent over an hour on this trying to figure out what to do.. here's the question
A nonuniform electric field is given by the expression E = ay^i + bz^j + cx^k,
where a, b, and c are constants. Determine the electric flux through a rectangular
surface in the xy plane, extending from x = 0 to x = w and from y = 0 to y = h.
this question can be viewed better here http://web.uvic.ca/~jalexndr/week%203%20problems.pdf (question #54)
i basically use gauss's law and get it down to something like
= C[tex]\int[/tex] (x dA )
my method here was two take the dot product of the electric field and dA which is said to be perpendicular to the surface in the x y plane therefore it will act along the z axis
so this dot product comes out equalling cxdA where c is a constant... where do i go from here.. the answer is given as (1/2 chw^2)
