What does your textbook say about 2.3 POTENTIAL DUE TO A POINT CHARGE?
Consider a point charge Q at the origin (Fig. . ). For definiteness, take Q to be positive. We wish to determine the potential at any point P with position vector r from the origin. For that we must calculate the work done in bringing a unit positive test charge from infinity to the point P. For Q > , the work done against the repulsive force on the test charge is positive. Since work done is independent of the path, we choose a convenient path – along the radial direction from infinity to the point P. At some intermediate point P′ on the path, the electrostatic force on a unit positive charge is ˆ '
