Equipotential lines for two charges

[Googl]

Hi there,

Could you describe for me what happens to the equipotential lines of two charges as they move close to each other.

Thanks

In the limiting case the two charges will be at one point, resembling the field of a single charge (with the magnitude of both charges combined.) So, when you move two like charges closer to each other, the equipotential lines will start to look more and more like that of a single charge.

Thanks, exactly when I have been looking for.

The charge's magnitude is twice that of original, though, which means that the equipotential lines will be packed more dense than with two single charges separated by great distance.
