Homework Statement
13 equal charges are placed in the corners of a regular 13-sided polygon. What is the force on a test chrage at the center?
Homework Equations
principle of superposition
symmetry
The Attempt at a Solution
I am not sure if the net force is 0 or not. Had the polygon been 12-sided the symmetry would be obvious, but I'm not sure in this case. Can anyone explain if the net force is 0 or not?
