• Neutral

• Negative

If you increase the magnitude of two charges, what happens to the force between them?

• The force is less than before

• The force is more than before

• The force remains unchanged

What is the difference between the Coulomb's force and gravitational force?

• Gravitational force is greater than Coulomb's force

• Coulomb's force is attractive, gravitational force is repulsive
