Which of the following sets of concurrent forces may be in equilibrium?
- A \(F_1=3 \mathrm{~N}, F_2=5 \mathrm{~N}, F_3=10 \mathrm{~N}\)
- B \(F_1=3 \mathrm{~N}, F_2=5 \mathrm{~N}, F_3=9 \mathrm{~N}\)
- C \(F_1=3 \mathrm{~N}, F_2=5 \mathrm{~N}, F_3=6 \mathrm{~N}\)
- D \(F_1=3 \mathrm{~N}, F_2=5 \mathrm{~N}, F_3=15 \mathrm{~N}\)
Answer & Solution
Correct Answer
(C) \(F_1=3 \mathrm{~N}, F_2=5 \mathrm{~N}, F_3=6 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
According to triangle law of forces, resultant of two forces must be greater than or equal to the third force. In option (a), \(F_1(3 \mathrm{~N})+F_3(1 \mathrm{~N}) F_3(6 \mathrm{~N})\) Hence, these sets of concurrent forces may be in equilibrium. In option (d),…
