AIIMS 2019 Physics Newton's Law of Gravitation MCQ Question
Assertion: Work done by or against gravitational force in moving a body from one point to another is independent of the actual path followed between the two points.
Reason: Gravitational forces are conservative forces.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The formula for gravitational force, F = Gm₁m₂/r², indicates that the gravitational attraction between two masses (m₁ and m₂) depends solely on their masses and the distance (r) between their centers, not on the path taken to measure that distance. This illustrates the principle of gravitational force being a central force, which acts along the line connecting the centers of the two masses, making it independent of the trajectory. Other options are not applicable as they do not provide relevant information or alternative answers to the question posed. Understanding this concept is crucial for grasping the nature of gravitational interactions in physics.
