When two equal forces F and F make an angle of 180o with each other, the magnitude of their resultant is:
Correct answer: C. 0
- A. F
- B. 2F
- C. 0
- D. 3F
Explanation
When two equal forces F and F make an angle of 180 degrees with each other, the magnitude of their resultant force is indeed 0. Here's the explanation: When two forces are equal in magnitude and opposite in direction, they cancel each other out. In this case, since the forces are making an angle of 180 degrees with each other, they are directly opposing each other. As a result, their combined effect is zero, and the resultant force has no magnitude. So, the magnitude of their resultant force is 0.

About Vectors and Equilibrium
Vectors have magnitude and direction, unlike scalars, and are combined by head-to-tail or parallelogram methods. Work covers rectangular components, equilibrium when the resultant force is zero, the scalar product for work and projections, and the vector product for torque and cross-product direction using the right-hand rule.
