How do you know if a force is attractive or repulsive?

Answer 1

Answer:

Explanation:

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

This called Coulomb's law and was the first attempt to understand the electric force. Like the gravitational force, the Coulomb force is an inverse square law.
