Chapter 18, Problem 27P

* Two $\text{- 3}\text{.0 }\times {\text{ 10}}^{\text{-9}}\text{- C}$ charged point-like objects are separated by 0.20 m. Determine the potential (assuming zero volts at infinity) at a point (a) halfway between the objects and (b) 0.20 m to the side of one of the objects (and 0.40 m from the other) along a line joining them.
