Homework Statement
Determine if the following diagrams may describe an electrostatic field in a charge-free space. The rectangles are the spaces under consideration. In the first four diagrams there are field lines while in the last two there are equipotential lines
Homework Equations
For the field lines, I used Gauss's law (in cgs):
div(E) = 4∏ρ
And for the potential diagrams, Earnshaw's theorem.
The Attempt at a Solution
I deduced that the upper-left and lower-left diagrams can describe such a field, but that was wrong.
Thanx.
