Homework Statement
The formula for Electric Potential as I have it is: "Let Q be a point source charge. At any point P that's a distance r from Q, we say that the electric potential at P is the scalar given by this formula:
electric potential = k * (Q/r)
My question is what if at some distance r from Q, the charge is very large. Wouldn't that then affect the electric potential. In other words how can this electric potential formula not take into account both charges and only takes into account Q which is the source charge?
