Type: MCQ-diagram based-Medium-Class 11
A diagram shows three forces F₁, F₂, and F₃ acting concurrently on a particle and forming a closed triangle with arrows in the same direction. Which condition must be satisfied for the particle to be in equilibrium under these forces?
A
F₁ + F₂ + F₃ = 0
B
F₁ = F₂ + F₃
C
F₁² + F₂² = F₃²
D
F₁ F₂ = F₃
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, equilibrium under three concurrent forces requires that the vector sum of the forces is zero, represented by a closed triangle.
