The electric potential at a point that is halfway between two identical charged particles is 300 V. What is the potential at a point that is 25% of the way from one particle to the other?

Answer: V2 = 400V

Explanation

We can start a solution with expression for the potential of a point charge:

 

In the middle between two charges potential is:

 

Potential at a point that is 25% of the wat from one particle to the other is:

 

If we substitute in the previous equation we get:
