Question

Assume the magnitude of the electric field on each face of the cube of edge L = 1.06 m in the figure above is uniform and the directions of the fields on each face are as indicated. (Take E1 = 35.4 N/C and E2 = 23.3 N/C.)

(a) Find the net electric flux through the cube.

(b) Find the net charge inside the cube.

Assume the magnitude of the electric field on each face of the cube of edge L = 1.06 m in the figure above is uniform and the directions of the fields on each face are as indicated. (Take E1 = 35.4 N/C and E2 = 23.3 N/C.) (a) Find the net electric flux through the cube. (b) Find the net charge inside the cube.

Explanation / Answer

a)

net flux = 1.06(20+20+20+15-35.4-23.3) = 17.278 N.M^2/C

b)

net charge = 17.278(8.85e-12) = 1.529e-10 C
