   * The electric field from the point charge at a particular observation location can be written as  $\vec{E} = \frac{1}{4\pi\epsilon_0}\frac{q}{r^2}\hat{r},$  where  $q$  represents the charge,  $r$  is the distance, and  $\hat r$  is the unit-vector pointing from the point charge source to the observation location.

 ===Assumptions===
-  * Point charge assumption: Necessary to use electric field equation.
   * Constant charge: Makes charge in electric field equation not dependent on time or space as no information is given in problem suggesting so.
   * Charge is not moving: This makes our separation vector fixed in time as a moving charge would have a changing separation vector with time.
