NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a diagram showing three equal masses of m kg each fixed at the vertices of an equilateral triangle ABC. What is the net gravitational force acting on a mass 2m placed at the centroid G of the triangle?
A
Zero due to symmetry of forces
B
2Gm^2/r^2 towards vertex A
C
3Gm^2/r^2 towards the centroid
D
Gm^2/r^2 towards vertex C
Correct Answer
Option A
Detailed Explanation
The forces from the three masses at the vertices of the triangle cancel out due to symmetry, resulting in a net force of zero on the mass at the centroid.
