Question

Name the force which holds the planets in their orbits around the sun.

• A. Gravitational force of attraction
• B. Electrostatic force of attraction
• C. Nuclear force of attarction
• D. Electromagnetic force of attraction

Answer 1

The correct option is A

Gravitational force of attraction

Explanation of option (A):

1. Gravitational force is the force responsible for holding planets in their orbits around the Sun.
2. The Sun contains 99.86% mass of the entire solar system and that is why it is able to keep the planets in their orbits.

Explanation of option (B):

1. The electrostatic force is also known as the Coulomb force or Coulomb interaction.
2. It's the attractive or repulsive force between two electrically charged objects.

Explanation of option (C):

1. The nuclear force is the force that binds the protons and neutrons in a nucleus together.
2. This force can exist between protons and protons, neutrons and protons, or neutrons and neutrons.
3. This force is what holds the nucleus together.

Explanation of option (D):

1. The electromagnetic force is a type of physical interaction that occurs between electrically charged particles.
2. It acts between charged particles and is the combination of all magnetic and electrical forces.
3. The electromagnetic force can be attractive or repulsive.

Therefore, option (A) is correct.
