Consider a closed triangular box resting within a horizontal electric field of magnitude E = 6.86 × 104 N/C as shown in the figure below.
30.0 cm
A closed right triangular box with its vertical side on the left and
downward slope on the right rests within a horizontal electric field
vector E that points from left to right. The box has a height of 10.0 cm
and a depth of 30.0 cm. The downward slope of the box makes an
angle of 60 degrees with the vertical.
(a) Calculate the electric flux through the vertical rectangular surface of the box.
kN • m?/c
(b) Calculate the electric flux through the slanted surface of the box.
kN • m?/c
(c) Calculate the electric flux through the entire surface of the box.
kN • m2/c
