NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): The gravitational force on a mass at the centroid of an equilateral triangle of masses is zero. | Reason (R): The gravitational forces from three equal masses at the vertices cancel each other at the centroid.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
In an equilateral triangle, the gravitational forces due to equal masses at the vertices acting on a mass at the centroid cancel out, resulting in zero net force. This is because the centroid is equidistant from all vertices.
