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 action-reaction pair.
• D. The gravitational force is a non-central force.

Answer 1

Answer: (C)

The gravitational force action-reaction pair.

Answer 2

The gravitations force is independent of the intervening medium. In other words, the force between two mass remains the same whether they are in air, vacuum, water or separated by a brick wall.

Hence, (1) is an incorrect statement.

The gravitational force is a conservative force.

Hence, (2) is an incorrect statement.

The gravitational force obeys newton’s third law of motion. Thus, it form action – reactions pair.

Hence, (3) is a correct statement.

The gravitational force is a central force. Hence, (4) is an incorrect statement.
