Question

_______ can both push and pull objects, whereas _______ can only pull them.

• A. Gravtitational force, magnetic force
• B. Electrostatic force, magnetic force
• C. Magnetic force, electrostatcic force
• D. Magnetic force, gravitational force

Answer 1

The correct option is D Magnetic force, gravitational force

Both magnetic force and electrostatic forces are either attractive or repulsive in nature. Unlike charges attract while like charges repel.
Similarly, unlike poles attract while like poles repel. On the other hand, gravitational force can only attract objects to the ground.
Thus, magnetic force can both push and pull objects, whereas gravitational force can only pull them.
