Question
The diagram shows a closed triangular prism situated in a region of uniform electric field E = (6.84 x 10^4 j) N/C. The dimensions of the triangular prism are a = 18.0 cm, b = 10.0 cm, and d = 32.4 cm. Note that the diagram is not to scale. (a) What is the flux through the bottom face of the triangular prism? What is the direction of the normal for the bottom face of the triangular prism? How is the flux through a face related to it (b) What is the flux through the slanted face of the triangular prism? What is the direction of the normal for the slanted face of the triangular prism? How is the flux through a face related to it (c) What is the flux through the front triangular face of the triangular prism? (d) What is the flux through the back triangular face of the triangular prism? (e) What is the flux through the vertical rectangular face of the triangular prism? (f) What is the net flux through the triangular prism? How is the net flux through the triangular prism related to the flux through each of these faces? N . m^2/CExplanation / Answer
a)
Here , flux = area * E
Flux = -0.18 * 0.324 * 6.84 *10^4
Flux = -3989.1 N.m^2/C
the flux is -3989.1 N.m^2/C
b)
flux through the slanted face = -flux thorugh the bottom
flux through the slanted face =3989.1 N.m^2/C
f)
net flux = 0 (as there is no charge inside the prism)
