Calculating Charge of a Cube given E using flux? - cube field 3
At each point on the surface of a cube, is the electric field is parallel to the axis Z. The length of each side of the cube 3,3 m. On the upper side of the cube E = -34 CN / C, and at the bottom of the cube = 19 K / C. Determine the net charge in the cube.
I calculated the net flow through the following procedure
RSS = -34 * (3.3) ^ 2 = -370.6
Bottom Flux = 19 * (3.3) ^ 2 = 163.35
Net Cash Flow (up) + flow (bottom) = -370.6 + 163.35
Cash flow = 206.91
First, I have this
Epsilon (none) * = net flow of charge (attached)
8.85E-12 * 163.35 =- 1.445E-9
What am I doing wrong?

The problem is to convert to kN / C to ... kN / CN / C
So it must be:
High-Flux = -34.000 * (3.3) ^ 2 = -370,600
Bottom Feed = 19000 * (3.3) ^ 2 = 163350
Net Cash Flow (up) + flow (bottom) = -370.600 + 163350
Net Cash = 206,910
You do not find the net flow, if you do not use e-form to the other 4 faces of the cube ...
unless there are other aspects of the proposal:
Qenco * = 8.854E 2.0691E5-12 = 1.83198E-6
