Question

Fill in the blank.

Like charges_________ each other while unlike ____________ charges each other.

• A. repel
• B. attract

Answer 1

1. Matter wants to possess a neutral state.
2. A negative charge wants to give away its electrons to become neutral therefore it attracts a positive charge towards it.
3. On the other hand, a positive charge requires electrons to become neutral, that is why it moves toward a negative charge.
4. Two same polarities of charge repel each other while two charges with different polarities attract each other.

Hence, like charges repel each other while unlike charges attract each other.
