Figure 1. Point charges and Gaussian sphere.
Two point charges, \(+Q\) and \(-Q\), are fixed on the x-axis at \(x = -d\) and \(x = +d\), respectively. The charges can be treated as ideal point charges. A mathematical Gaussian sphere of radius \(R = d/2\) is defined such that its center can be moved continuously along the x-axis.
