  • Two charges –q and +q are located at points (0, 0, –a) and (0, 0, a), respectively. Obtain the dependence of potential on the distance r of a point from the origin when r/a >> 1.

2.21 Two charges –q and +q are located at points (0, 0, –a) and (0, 0, a), respectively. 

(b) Obtain the dependence of potential on the distance r of a point from the origin when  \frac{r}{a}>>1

Here, since distance r is much greater than half the distance between charges, the potential V at a distance r is inversely proportional to the square of the distance 

V\propto \frac{1}{r^2}
