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

Options

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

Answer

C

Explanation

( c) The gravitational force is independent of the intevening medium, In other words, the force between two masses remains the same whether they are in air, vaccum, 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 a action-reaction pair.
Hence, (c ) is a correct statement.
The gravitational force is a central force. Hence, (d) is an incorrect statement .
