Question

Identify the force which has a tendency to pull all objects towards the center of the Earth.

• A. Force of friction
• B. Force of gravity
• C. Electrostatic force

Answer 1

The correct option is B

Force of gravity

The explanation for the correct option:

Option (B): Force of gravity

1. It is an attractive force that pulls the objects.
2. It can act between objects that may or may not be in direct contact with each other.
3. The force of gravity is maximum at the surface of the Earth.
4. So, the force of gravity has the tendency to pull all objects towards the center of Earth.

The explanation for the incorrect options:

Option (A): Force of friction.

1. It is a contact force.
2. It takes place between the two bodies when they rub against each other.
3. It is an opposing force and always resists motion.

Option (C): Electrostatic force:

1. It is an attractive/repulsive force.
2. It occurs between two charged bodies or one charged and another uncharged body.

Hence, option B is the correct answer.
