Question

Which of the following statements is correct regarding the gravitational force?

• A. The gravitational force is dependent on the intervening medium.
• B. The gravitational force is a non-conservative force.
• C. The gravitational force forms action-reaction pair.
• D. The gravitational force is a non-central force.

Answer 1

Answer: (C)

The gravitational force forms action-reaction pair.

The gravitational force is independent of the intervening medium. In other words, the force between two masses remains the same whether they are in air, vacuum, water or separated by a brick wall.Hence, (a) is an incorrect statement.

The gravitational force is a conservative force.Hence, (b) is an incorrect statement.

The gravitational force obeys Newton's third law of motion. Thus, it form action-reaction pair.Hence, (c) is a correct statement.

The gravitational force is a central force. Hence, (d) is an incorrect statement.
