STANDARD Physics Gravitational Force MCQ Question
Three masses each of mass m are placed at the vertices of an equilateral triangle ABC of side l as shown in figure. The force acting on a mass 2m placed at the centroid O of the triangle is
Zero
3Gm²/l²
5Gm²/l²
7Gm²/l²
Correct Answer
Detailed Explanation
The forces due to the masses at the vertices of the triangle cancel each other out at the centroid due to symmetry, resulting in a net force of zero.
