Hey guys, I want to ask a question about the Coulomb force or the electrostatic force.
As you can see, there are these statement,
1) The electric force is a "vector quantity"
2) The electric force between two stationary charged objects is called the Electrostatic force.
3) The electrostatic force between two charges can be repulsive or attractive.
And my problems are for each question:
1) If an electric force is a vector quantity. Then why do we call the force between two charges "force" because it should be "forces" as there are two vectors in the case of "Coulomb's law"
2)+3) I only know what is called "the magnitude of the electrostatic force is F=k q1 q2/ r^2. But what is the electrostatic force.
Does the term "electrostatic force means (for example in the picture)" ?
1. The vector FQq and the vector FqQ combined.
2. Either the vector FQq or the vector FqQ.
