Let \( \vec{r_{1}} \) be the displacement of a charge \( Q \), and let \( \vec{r_{2}} \) be the displacement of a charge \( q \), where these two charges are named \( P_{1}\) and \( P_{2} \) respectively. @@ -53,6 +56,9 @@ but since this is electrostatics and not electrodynamics, you will not have to w magnetic constants.

Let's call \( P_{1} \) our /test charge/, and \( P_{2} \) our /source charge/. If we now want to measure the force on \( P_{1} \), our equation is going to be the same. However, we can define a field \( \vec{E(\vec{r})} \) such that: |
