A system is brought to equilibrium by applying a force equal in magnitude to the resultant force but opposite in direction. This applied force is called the
AEquilibrant
BResultant force
CCentripetal force
DImpulsive force
Answer & Solution
Correct answer: A. Equilibrant
1. The resultant is the single force replacing all forces acting on a body.
2. To cancel it and reach equilibrium, an equal and opposite force is needed.
3. This balancing force is called the equilibrant.
4. Rule out resultant force: that is the net force being cancelled, not the balancing one.
