Three concurrent co-planar forces \(1 \mathrm{~N}, 2 \mathrm{~N}\) and \(3 \mathrm{~N}\) acting along different directions on a body
- A can keep the body in equilibrium if \(2 \mathrm{~N}\) and \(3 \mathrm{~N}\) act at right angle
- B can keep the body in equilibrium if \(1 \mathrm{~N}\) and \(2 \mathrm{~N}\) act at right angle
- C cannot keep the body in equilibrium
- D can keep the body in equilibrium in \(1 \mathrm{~N}\) and \(3 \mathrm{~N}\) act at an acute angle
Answer & Solution
Correct Answer
(C) cannot keep the body in equilibrium
Step-by-step Solution
Detailed explanation
If we keep \(1 \mathrm{~N}\) and \(2 \mathrm{~N}\) forces act in same direction then these are balanced by \(3 \mathrm{~N}\) force, but this is against statement of question. Hence, options (c) is correct.
