### Question Description

Information: You have 2 elongated wires. These wires are parallel to the z axis. They have line charge densities denoted K1 and -K2. There are specific cases when the equipotential surfaces combine cylinders that are centered at the origin and parallel to the z axis.

Problem:

Find an equation that fits this case and explain your answer in detail. In your answer display that if x1=K2=0, then the equation must demonstrate that the cylinder that is centered on the z axis is in fact an equipotential. Lastly, give one extra definitive solution as well.
