Electrostatic potential caused by two point chargesWhat is the difference in electrostatic potential $\varphi(\vec{r}_A) - \varphi(\vec{r}_B)$ between positions $\vec{r}_A$ and $\vec{r}_B$, , caused by two point charges $q_1$ and $q_2$? Point charge $q_1=$ × 10-12 [C] is located at [μm], and point charge $q_2=$ × 10-11 [C] is located at [μm]. |
