Minimum number of equal forces that keep the body in equilibrium are:
Correct answer: A. Two
- A. Two
- B. Three
- C. Four
- D. Five
Explanation
Consider a particle having just one line of force acting on it. This force results in acceleration of the particle disturbing its equilibrium. The minimum number of equal forces required to keep a body in equilibrium is two. These forces must be equal in magnitude and opposite in direction to balance each other out and result in a net force of zero.

About Addition of Vectors
Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
