A positively charged particle is placed near a negatively charged particle. What is the direction of the electric force between the two particles?
The electric force is directed from the negative particle to the positive particle.
The electric force is zero.
The direction of the electric force cannot be determined.
The electric force is directed from the positive particle to the negative particle.
설명
The electric force between two charged particles is always directed from the positive particle to the negative particle. This is because opposite charges attract each other, while like charges repel each other.
