A point charge \(+q\) is fixed at the origin \(x = 0\), and a second point charge \(-2q\) is fixed at \(x = d\) along the \(x\)-axis. Electric potential is defined to be zero at an infinite distance from the charges. At what position on the \(x\)-axis between the two charges is the net electric potential equal to zero, and what is the status of the net electric field at that same position?
