 Where \( \hat{r} \) is the unit vector pointing in the direction of \( P_{2} \). Note that there are a
 couple of interesting things about this force. First, it is an [[id:2a543b79-33a0-4bc8-bd1c-e4d693666aba][inverse square]] law, and the formula looks a lot like the one for gravitation,
 only charge can be negative and mass cannot. Second, it is symmetrical,
 in the sense that the force felt by \( P_{2} \) is going to be the same, only \( \hat{r} \)
-is pointing in the other direction. Also, note that due to linearity, this force calculation follows the /superposition principle/.

 because we often want to find the force if an arbitrary object with an arbitrary charge is next
 to the particle in question, instead of focusing specifically on two charges.
