NEET Physics Gravitational Force Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 11
Statement – I: 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 2 m placed at the centroid O of the triangle is zero. Statement – II: If the mass placed at vertex A is doubled, then the force acting on the mass 2m placed at the centroid O is 6Gm²/l².
A
Statement I is false but Statement II is true
B
Statement I is true but Statement II is false
C
Both Statement I and Statement II are true
D
Both Statement I and Statement II are false
Correct Answer
Option C
Detailed Explanation
In an equilateral triangle, the centroid is at an equal distance from all vertices, so the net gravitational force is zero. Doubling the mass at one vertex creates a net force.
