Final answer:
The force that acts between the electron and nucleus of an atom is the electromagnetic force, while the force that keeps the planets in their orbits is the gravitational force.
Step-by-step explanation:
b) False
The force that acts between the electron and nucleus of an atom is the electromagnetic force. It is a force of attraction between the negatively charged electron and the positively charged nucleus. On the other hand, the force that keeps the planets in their orbits around the Sun is the gravitational force. It is a force of attraction between any two objects with mass, such as the planets and the Sun. Although both forces are fundamental forces in nature, they are distinct and have different characteristics. The electromagnetic force acts between charged particles, while the gravitational force acts between all objects with mass.
