NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram showing three equal masses m fixed at the vertices of an equilateral triangle ABC. A mass 2m is placed at the centroid G of the triangle. If the mass at vertex A is doubled, what is the net gravitational force acting on the mass 2m at the centroid?
A
The net force remains zero due to symmetry.
B
The net force acts towards vertex A due to increased mass.
C
The net force acts away from vertex A due to increased mass.
D
The net force acts perpendicular to side BC due to symmetry.
Correct Answer
Option B
Detailed Explanation
When the mass at vertex A is doubled, the symmetry is broken, resulting in a net gravitational force on the mass 2m at the centroid, directed towards vertex A.
