Hello, the problem I am working on is:
Assume the magnitude of the electric field on each face of the cube of edge L = 1.05 m in the figure below is uniform and the directions of the fields on each face are as indicated. (Take E1 = 31.5 N/C and E2 = 26.5 N/C.)
(a) Find the net electric flux through the cube.
(b) Find the net charge inside the cube.
(c) Could the net charge be a single point charge?
I attached the diagram in my post.
The Attempt at a Solution
I was able to answer all but part (c) properly. I answered yes. Is it false because there aren't any electric field lines flowing out from the cube through one of the surfaces?
