anonymous · Answer

ok, I have an integral question though

anonymous · Answer

$$\int_{x_1}^{X_2} \frac{kcos\theta\lambda dx_2}{r^2}$$

phi · Answer

The flux is the part of E normal to the surface.  So to answer your question
how does the E on top penetrate the surface and is still parallel to the surface?  It doesn't 
the flux through the sides is 0

Oh interesting
