Two forces of magnitude F1 and F2 are acting on an object.The magnitude of the net force Fnet on the object will be in the(A) F­1 ≤ F net ≥ F2. (B) (F1 – F2)/2 ≤ Fnet ≤ (F1 + F2)/2.(C) |F1-F2| ≤ Fnet ≤ |F1 + F2|.

Assume that the force F₁ on an object makes an angle with F₂ on object, such that the component of force F₁ along F₂ is F₁cos and component of force perpendicular to F₂ is F₁ sin.
The sum of the forces along the direction of force F₂ is F₂+F₁ cos , and the sum of the forces along the direction perpendicular to F₂ is F₁sin . Therefore the magnitude of net force acting on the object is:

The magnitude of minimum force is:
