Concept:A single equivalent force that represents the combined effect of several forces acting together is called the resultant force.
Explanation:When two or more forces act at the same point, their individual effects can be combined into one force.
This combining process is known as vector addition, and the single force obtained is the resultant.
The resultant force produces exactly the same effect on the body as the original set of forces.
The equilibrant, however, is equal in magnitude but opposite in direction to the resultant, and it keeps the forces balanced.
A component is simply one part of a force acting in a specific direction, not the combined effect.
Thus, the term that matches the definition is "resultant."
Answer:C. resultant
