Let's consider point P to be at a distance d to the left of the first charge.
A -10.0nC point charge and a +20.0nC point charge are 15.0cm apart on the x-axis. What is the electric potential at the point on the x-axis where the electric field is zero? What is the magnitude of the electric field at the point on the x-axis, between the charges, where the electric potential is zero? What is the direction of the electric field at the point on the x-axis, between the charges, where the electric potential is zero?
