Assignment:
Draw a picture of the electric field lines generated by a collection of two positive charges, both of charge q = 1. Center one at (1,0) and the other rat (-1,0). What happens to the electric field at the origin? (the point 0,0)
Draw a few equipotential lines. Remember, these are the curves that circle the charge distribution, always perpendicular to the electric field lines.
Is the electric potential at the origin zero or nonzero?
Provide complete and step by step solution for the question and show calculations and use formulas.
