NEET Physics Universal Law of Gravitation MCQ Question
Consider a diagram where two point masses, m1 and m2, are shown with a distance r between them. The unit vector from m1 to m2 is labeled as r̂. Which of the following correctly describes the gravitational force F12 on m1 due to m2?
F12 is along the direction of r̂.
F12 is opposite to the direction of r̂.
F12 is perpendicular to the direction of r̂.
F12 does not depend on the direction of r̂.
Correct Answer
Detailed Explanation
The gravitational force is attractive, meaning F12 on m1 due to m2 is along -r̂, opposite to the direction of r̂ as per Newton’s law of gravitation.
