Module 2 : Electrostatics
Lecture 10 : Potential Energy of a System of Charges

Example 17:

Determine the equipotential surface for a point charge.

Solution :

Let the point charge $q$be located at the origin. The equation to the equipotential surface is given by

\begin{displaymath}\phi(x,y,z) = \frac{1}{4\pi\epsilon_0}\frac{q}{\sqrt{x^2+y^2+z^2}} = \phi_0= {\rm constant}\end{displaymath}
