# Electronics/Physics related question which is mostly mathematics - on topic here?

I have a question which is related to a physical topic (force of one charge on another).
In fact this specific question is about a charged ring with a radius $$R$$ and a charge in z-direction in distance $$d$$.
The approach here would be to find an equation / integral based on these vectors (don't want to be too specific as this question is "meta").
Intuitively I'd ask this question here because it's mostly calculating with vectors but as it's also physics related, so I'm uncertain about where to ask this question.
