Answer 2

Answer: A. electric and magnetic forces

Explanation:

• Magnetic force acts between two magnetic objects. A magnet has two poles- North pole and South pole. Like poles repel each other and unlike poles attract each other.

• Electric force acts between two charged objects. Two similarly charged bodies have repulsive force between them and attractive force exists between two dissimilar charged objects.

Thus, an electric force and magnetic force are repulsive and attractive in nature.
