Question: A -10.0 nC point charge and a +20.0 nC point charge are 14.7 cm apart on the x-axis.
A) What is the electric potential at the point on the x-axis where the electric field is zero? (I found that this was 105 V)
B) What is the magnitude of the electric field at the point on the x-axis, between the charges, where the electric potential is zero?
