Short Answer
6 N is the best answer.
This concept lives inside the mechanics toolkit: forces, motion, energy, momentum, and rotation. The safest way to solve it is to name the governing law first, then connect the variables in units you trust.
F = ma = 2 × 3 = 6 N.
Why This Answer Is Correct
This is a Easy-level question in Classical Mechanics. The prompt is really testing whether you can connect the concept to its defining physical relationship instead of picking a nearby-but-wrong term.
Mechanics questions usually become easier once you identify whether the problem is about force balance, kinematics, energy, or conservation.
Choices At A Glance
- A. 1.5 N
- B. 5 N
- C. 6 N
- D. 8 N
When similar options appear on an exam, eliminate the ones that break the core law, use the wrong units, or confuse a definition with a consequence.
