Two -3.0 Af-10Acˆ'6 C charged point-like objects are separated by 0.20 m.
a) Determine the potential (assuming zero volts at infinity) at a point halfway between the objects.
b) Determine the potential (assuming zero volts at infinity) at a point 0.20 m to the side of one of the objects (and 0.40 m from the other) along a line joining them.
