A charge of -2.20 microcoulombs is located at (3.00m, 4.50m), and a charge of +3.60 microcoulombs is located at (-2.8m, 0m)
i.) What is the electric potential at the origin?
ii.) There is one point on the line between the two charges where the electric potential is equal to zero. What is the x-y components of this point?
