Find the points where electric potential is zero?

[QUOTE="jbriggs444, post: 4751119, member: 422467"] That is because there is no solution. Potential at a point can be defined as the work needed to bring a unit charge from infinity to that point. As long as the 2C and 3C charges both have the same sign, the path from infinity to any finite point will be uphill against a non-zero electrical force all (or most) of the way. So all finite points will have positive potential. A more rigorous way to see it is that the potential field from the 2C charge is clearly positive everywhere. And the potential field from the 3C charge is also clearly positive everywhere. The combined field from both is just the sum. It must also be positive everywhere. [/QUOTE]
