Neco Model Questions Vol1 2024 Physics Question 1 diagram

From the force diagram, a particle is acted upon by three coplanar forces. Force \(F_{1}\) has magnitude 30 N and is directed horizontally to the right. Force \(F_{2}\) has magnitude 40 N and makes an angle of \(120^{\circ}\) measured counter‑clockwise from the positive x‑axis. The third force \(F_{3}\) acts in a direction that makes the particle in equilibrium (its direction is unknown). Calculate the magnitude of \(F_{3}\) (in newtons).

Answer Options

A. 10\\sqrt{12} \\text{ N} \\; (\\approx 34.6 \\text{ N})
B. 12\\sqrt{13} \\text{ N} \\; (\\approx 43.3 \\text{ N})
Correct Answer C. 10\sqrt{13} \text{ N} \; (\approx 36.1 \text{ N})
D. 8\\sqrt{13} \\text{ N} \\; (\\approx 28.8 \\text{ N})
Correct Answer
C
Correct Option:
10\sqrt{13} \text{ N} \; (\approx 36.1 \text{ N})
