If the two opposing forces act on an object, the net force acting on it is the Correct Answer Difference between two forces

The correct answer is option 2) i.e. Difference between two forces

CONCEPT:

  • The net force is the vector sum of the forces acting on an object. 
    • The appropriate sign convention is used while summing the force vectors.
    • The net force is always directed in the direction of the larger force among the forces acting on an object.

EXPLANATION:

​Let the two opposing forces acting on an object B be F1 and F2.

Consider the forces to the upward direction as positive and that to the downward direction as negative.

From the diagram, the net force = (+ F1) + (- F2) = F1 - F2 ⇒ difference between the forces.
