Step 1
What do the letters $F$, $q$, and $d$ stand for in this expression?
Answer
In Coulomb's law, the letters represent the following:
- : This stands for the force between two point charges. It is a vector quantity that indicates the strength and direction of the interaction between the charges.
- : This denotes the charge of the particles involved. Each individual charge can be represented as and respectively.
- : This represents the distance between the centers of the two charges. It is crucial for calculating the electrostatic force according to the inverse square law.
