Question

Electric Fields and Potentials---- lab

A) What does it imply about the electric field when the electric potential is zero?

B) Using the standard convention that V = 0 infinitely far from a charge, in the case of a single positive point charge is it ever possible to find a location where the electric potential is negative? Reason?

C) The simulation only shows two spatial dimensions whereas we live in a world with three. What do you think the shapes of the equipotential surfaces of a single point charge are in three dimensions?
