Physics-Universal Law of Gravitation
NEET Physics Universal Law of Gravitation MCQ Question
Type: MCQ-diagram based-Easy-Class 11
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?
A
F12 is along the direction of r̂.
B
F12 is opposite to the direction of r̂.
C
F12 is perpendicular to the direction of r̂.
D
F12 does not depend on the direction of r̂.
Correct Answer
Option B
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.
