A 3.10μC and a -1.91 μC charge are placed 3.56 cm apart.At what points along the line joining them is the potential zero?

I calculated one point to be 2.20cm but I don't know how to get the other point.

What about infinity?

Infinity is incorrect. How does that even make sense there? Switch the signs in your denominator
