-Suppose we have a positively charged balloon with total charge $Q=5\cdot 10^{-9} \text{ C}$. What is the electric potential (also called voltage) at a point $P$, which is a distance $R=50 \text{ cm}$ from the center of the balloon?
+===== Example: Electric Potential from a Positively Charged Balloon =====
+Suppose we have a positively charged balloon with total charge $Q=5.0\cdot 10^{-9} \text{ C}$. What is the electric potential (also called voltage) at a point $P$, which is a distance $R=50 \text{ cm}$ from the center of the balloon?
 ===Facts===
-  * The balloon has total charge $Q=5\cdot 10^{-9} \text{ C}$.
+  * The balloon has total charge $Q=5.0\cdot 10^{-9} \text{ C}$.
   * The point $P$ is a distance $R=50 \text{ cm}$ away from the center of the balloon.
   * The electric potential due to a point charge can be written as $$V = \frac{1}{4\pi\epsilon_0}\frac{q}{r},$$ where $q$ represents the charge and $r$ is the distance.

-The electric potential infinitely far away from the balloon is $0 \text{ V}$. Read [184_notes:superposition#Superposition_of_Electric_Potential|here]] for why this is important.
