I don't know if the following generalization exists, but I want to give it a go. If you want to join, please do and help me. For this mini research to be a success, you need to help me with this problem. I found this to be little tricky and confusing stuff. Here it is.
Here is a regular pentagon named \(ABCDE\). Suppose, equal charges \(q\) are placed on each of its vertex.Now here's the calculation I need from your side. Find the magnitude of the net force exerted on a charge by the other \(4\) charges.
Details and Assumptions:
The length of each side of the pentagon is assumed to be \(a\).
Assume the medium to be vacuum.
