Hello , If i was given two or three charges separated , and they all lie on the same straight line ... how can I identify the neutral point ?

* Take any value for their separation , their charges and sign if you want to give an example ,, just a general question

How about writing down the potential as a function of the position and minimising/maximising it?

Try to answer the following: What is the electric potential from a point charge? How does the electric potential change when you add another charge? What is the defining property of a stable point?
