Question

The force of attraction between the Earth and the Moon is

• A. Magnetic force
• B. Gravitational force
• C. Mechanical force
• D. Electrostatic force

Answer 1

The correct option is B

Gravitational force

B: Gravitational force

Explanation for the correct option

1. It is a type of non-contact force explained by Newton.
2. Non-contact forces are the type of forces that act between objects when they are far from each other or not in direct contact with each other.
3. It is a force of attraction between two bodies having mass.
4. Example: The force of attraction between the Earth and the Sun because of which the Earth revolves around the sun.

Explanation for incorrect options

A: Magnetic force

1. It is a type of non-contact force between two magnets.
2. Non-contact forces are the type of forces that act between objects when they are far from each other or not in direct contact with each other.
3. Magnetic force is the force of attraction or repulsion between two magnets when they are kept near to each other.
4. It is the force experienced by a magnet or a metal kept near another magnet.

C: Mechanical Force

1. A force that is exerted by a machine is called mechanical force.
2. In order to push a heap of rubble, a bulldozer generates some amount of force.
3. This force exerted by the bulldozer is called mechanical force.

D: Electrostatic force

1. It is a type of non-contact force explained by Coulomb.
2. Non-contact forces are the type of forces that act between objects when they are far from each other or not in direct contact with each other.
3. The force of attraction or repulsion between two charged bodies is called electrostatic force.
4. Example: When we rub our hair with a balloon, some of the charges get transferred from balloon to hair making them electrically charged.
5. An electrostatic force of attraction starts to act between hair and balloon.

Hence, the force of attraction between the Earth and the Moon is the gravitational force.

Thus, option (b) is correct.
