A box of mass \(m\) is in equilibrium under the application of three forces as shown below. If the magnitude of \(\mathbf{F}_1\) is \(10 \mathrm{~N}\), what is the magnitude of \(\mathbf{F}_3\) ?
- A 5N
- B 15 N
- C 20 N
- D 30 N
Answer & Solution
Correct Answer
(C) 20 N
Step-by-step Solution
Detailed explanation
All forces are resolved in two perpendicular axes \((X\) and \(Y)\) as shown in the figure. Since, block of mass \(m\) is in equilibrium. Hence, resolving the forces in \(x\)-direction, we get…
