NEET Physics Equilibrium of Forces MCQ Question
Which of the following combinations correctly describes the conditions for the equilibrium of forces acting on a particle?
The vector sum of all forces acting on the particle must be zero.
The forces must be equal in magnitude but not necessarily in direction.
The forces can be represented as the sides of a triangle.
The resultant force from any two forces must be equal to a third force acting on the particle.
Correct Answer
Detailed Explanation
According to the NCERT context, for a particle to be in equilibrium, the vector sum of all forces acting on it must indeed be zero (F1 + F2 + F3 = 0). Additionally, the condition can be represented geometrically as the sides of a triangle, but the most fundamental requirement is that the vector sum equals zero.
