Question

describe the difference between repulsion and attraction and how the signs of the charges determine which action occurs. (page 124)

Explanation:

Repulsion is when two objects push away from each other. Attraction is when two objects pull towards each other. In terms of charges, like charges (both positive or both negative) repel each other. Opposite charges (one positive and one negative) attract each other.

Answer:

Repulsion is a pushing - away force, attraction is a pulling - towards force. Like charges cause repulsion, opposite charges cause attraction.
