Problem 1: electric flux through a wedge 60 Consider a closed triangular box resting within a horizontal electric field of magnitude E as shown in the figure. The height of the box is h, the horizontal width is W and the depth is D into the page. Find an expression for the electric flux through: a) the vertical rectangular surface, b) the slanted surface, and c) the entire surface of the box. Show each step of your calculation.
