(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A square surface, 34 mm each side, is immersed with an electric field of magnitude 1700 N/C. The field lines make a 35 degree angle with the normal line. Find the electric flux through the surface.

2. Relevant equations

[itex]\oint[/itex]E[itex]\cdot[/itex]dA

3. The attempt at a solution

Well, since E[itex]\cdot[/itex]dA can be rewritten as EA*cos([itex]\Theta[/itex]), I did that, and since E and Cos([itex]\Theta[/itex]) are constants, I pulled them out of the integral giving me

E*Cos([itex]\Theta[/itex])[itex]\oint[/itex]dA

which comes out to be E*Cos([itex]\Theta[/itex])*A, but when I plug in 1700*Cos(35)*.0034[itex]^{2}[/itex] it's wrong.

Any suggestions?
