NEET Physics Equilibrium of Forces MCQ Question
Which of the following statements about the equilibrium of forces is correct?
The vector sum of three concurrent forces must equal zero for equilibrium.
Any two forces can be in equilibrium without considering a third force.
Forces in equilibrium can be represented as the sides of an open polygon.
Equilibrium can occur with more than three forces only if they are all equal.
Correct Answer
Detailed Explanation
The correct statement is that the vector sum of three concurrent forces must equal zero for equilibrium, as stated in the NCERT context. This means that the forces can be represented by the sides of a closed polygon, not an open one.
